Seeing the Unseen: How LiDAR Scanning is Transforming Mining Process Plants

In modern mining, where uptime is money and safety is non-negotiable, understanding the geometry of your process plant is critical. Every conveyor, chute, pipe rack, and piece of equipment must fit together seamlessly and operate reliably โ€” but plants are messy, dusty, and constantly changing. Manual measurement with a tape or total station is slow, risky, and often incomplete.

Labels highlight applications such as stockpile volumetrics, crusher inspections, safety and risk management, chute wear and blockages, mill wear measurement, tank deformation monitoring and creating digital twins.

This is where LiDAR scanning (Light Detection and Ranging) has become a game-changer. By capturing millions of precise 3D points per second, LiDAR gives engineers, maintenance planners, and operators an exact digital replica of the plant โ€” without climbing scaffolds or shutting down equipment. In this post, weโ€™ll explore how mining companies are using LiDAR scanning to solve real problems in processing plants, improve safety, and unlock operational efficiency.


What Is LiDAR Scanning?

LiDAR is a remote sensing technology that measures distance by firing pulses of laser light and recording the time it takes for them to return. Modern terrestrial and mobile LiDAR scanners can:

  • Capture hundreds of thousands to millions of points per second
  • Reach tens to hundreds of meters, depending on the instrument
  • Achieve millimeter-to-centimeter accuracy
  • Work in GPS-denied environments, such as inside mills, tunnels, or enclosed plants (using SLAM โ€” Simultaneous Localization and Mapping)

The output is a point cloud โ€” a dense 3D dataset representing surfaces, equipment, and structures with stunning accuracy. This point cloud can be used as-is for measurements or converted into CAD models and digital twins.


Why Process Plants Are Perfect for LiDAR

Unlike greenfield mine sites, processing plants are some of the most geometry-rich and access-constrained areas on site. They contain:

  • Complex networks of pipes, conveyors, tanks, and structural steel
  • Moving equipment such as crushers, mills, and feeders
  • Dusty, noisy, and hazardous environments with limited safe access

All these factors make traditional surveying difficult โ€” and sometimes dangerous. LiDAR enables โ€œno-touchโ€ measurement from safe vantage points, even during operation. Multiple scans can be stitched together to create a complete model without shutting down the plant.


Applications of LiDAR in Process Plants

1. Wear Measurement and Maintenance Planning

LiDAR has revolutionized how mines measure and predict wear on critical process equipment:

  • SAG and Ball Mill Liners โ€“ Portable laser scanners can capture the exact wear profile of liners. Comparing scans over time reveals wear rates, helping maintenance teams schedule relines with confidence and avoid premature failures.
  • Crusher Chambers โ€“ Scanning inside primary and secondary crushers is now faster and safer than manual inspections. The resulting 3D model allows engineers to assess liner life and optimize chamber profiles.
  • Chutes and Hoppers โ€“ Internal scans show where material buildup occurs, enabling targeted cleaning and redesign to prevent blockages.

Result: Reduced downtime, safer inspections, and better forecasting of maintenance budgets.


2. Retrofit and Expansion Projects

When modifying a plant โ€” installing a new pump, rerouting a pipe, or adding an entire circuit โ€” having an accurate โ€œas-builtโ€ model is crucial.

  • As-Built Capture โ€“ LiDAR provides an exact snapshot of the existing plant layout, eliminating guesswork.
  • Clash Detection โ€“ Designers can overlay new equipment models onto the point cloud to detect interferences before anything is fabricated.
  • Shutdown Optimization โ€“ With accurate geometry, crews know exactly what to cut, weld, and install โ€” reducing surprise field modifications and shortening shutdown durations.

3. Inventory and Material Flow Monitoring

LiDAR is not just for geometry โ€” itโ€™s also a powerful tool for tracking material:

  • Stockpile Volumetrics โ€“ Mounted scanners on stackers or at fixed points can monitor ore, concentrate, and product stockpiles in real time.
  • Conveyor Load Measurement โ€“ Stationary LiDAR above belts calculates volumetric flow, giving a direct measure of throughput without contact.
  • Blending Control โ€“ Accurate inventory data improves blending plans, ensuring consistent plant feed quality.

4. Safety and Risk Management

Perhaps the most valuable application of LiDAR is keeping people out of harmโ€™s way:

  • Hazardous Floor Areas โ€“ When flooring or gratings fail, robots or drones with LiDAR payloads can enter the area and collect data remotely.
  • Fall-of-Ground Risk โ€“ High walls, bin drawpoints, and ore passes can be scanned for unstable rock or buildup.
  • Escape Route Validation โ€“ Scans verify clearances for egress ladders, walkways, and platforms.

Every scan effectively becomes a permanent digital record โ€” a baseline for monitoring ongoing structural integrity.


5. Digital Twins and Advanced Analytics

A plant-wide LiDAR scan is the foundation of a digital twin โ€” a living, data-rich 3D model connected to operational data:

  • Combine scans with SCADA, IoT, and maintenance systems
  • Visualize live process variables in context (flow rates, temperatures, vibrations)
  • Run โ€œwhat-ifโ€ simulations for debottlenecking or energy optimization

As AI and simulation tools mature, the combination of geometric fidelity and operational data opens new possibilities for predictive maintenance and autonomous plant operations.


Emerging Opportunities

Looking forward, there are several promising areas for LiDAR in mining process plants:

  • Autonomous Scan Missions โ€“ Using quadruped robots (like Spot) or SLAM-enabled drones to perform routine scanning in high-risk zones.
  • Real-Time Change Detection โ€“ Continuous scanning of critical assets with alerts when deformation exceeds thresholds.
  • AI-Driven Point Cloud Analysis โ€“ Automatic object recognition (valves, flanges, motors) to speed up model creation and condition reporting.
  • Integrated Planning Dashboards โ€“ Combining LiDAR scans, work orders, and shutdown schedules in a single interactive 3D environment.

Best Practices for Implementing LiDAR

To maximize the value of LiDAR scanning, consider:

  1. Define the Objective โ€“ Are you measuring wear, planning a retrofit, or building a digital twin? This affects scanner choice and resolution.
  2. Plan Scan Positions โ€“ Minimize occlusions and shadow zones by preplanning vantage points.
  3. Use Proper Registration โ€“ Tie scans to a control network for consistent alignment between surveys.
  4. Mind the Environment โ€“ Dust, fog, and vibration can degrade data; choose scanners with appropriate filters or protective housings.
  5. Invest in Processing Tools โ€“ The raw point cloud is only the start โ€” software for meshing, modeling, and analysis is where value is extracted.
  6. Train Your Team โ€“ Build internal capability for scanning, processing, and interpreting the results to avoid vendor bottlenecks.

Infographic showing a 3D LiDAR scanner on a tripod surrounded by eight best-practice principles: start with clear objectives, plan your scanning campaign, prioritize safety, optimize data quality, ensure robust registration and georeferencing, establish repeatability, integrate with downstream systems, and train people with documented procedures

LiDAR scanning is no longer a niche technology โ€” it is rapidly becoming a standard tool for mining process plants that want to operate safely, efficiently, and with fewer surprises. From mill liners to stockpiles, from shutdown planning to digital twins, LiDAR provides a clear, measurable view of assets that was impossible a decade ago.

For operations teams under pressure to deliver more with less, the case is compelling: better data leads to better decisions. And in a high-stakes environment like mineral processing, better decisions translate directly to improved uptime, reduced costs, and safer workplaces.

The next time youโ€™re planning a shutdown, a retrofit, or even just trying to understand why a chute is plugging, consider pointing a LiDAR scanner at the problem. You may be surprised at how much more you can see โ€” and how much time and money you can save.

Lessons from a Landmark Case:

The Importance of Robust Structural Design Review

In 2024, SafeWork SA concluded a landmark case involving a spectator-roof collapse during a football club redevelopment project in South Australia. While no life-threatening injuries occurred, the incident highlighted how critical it is for design, review, and certification processes to work together to ensure safety on site.

This was the first successful design-related prosecution under South Australiaโ€™s Work Health and Safety Act, sending a clear signal to the engineering and construction sector: design decisions carry legal and safety obligations, not just technical ones.

Infographic titled โ€œLessons from a Landmark Case,โ€ showing engineers reviewing a design, icons highlighting robust review procedures, proper certification, time-pressure risks, and legal design responsibilities. The lower illustration depicts a structure collapsing after four column failures with two workers falling, emphasising the message โ€œSafety starts at the drawing board

What Happened (Briefly)

During roof sheeting works in late 2021, four of seven supporting columns of a cantilevered spectator roof failed, causing two apprentices to slide down the roof sheets. SafeWork SAโ€™s investigation found that the anchor bolts specified for the column base plates were inadequate and did not meet the requirements of the National Construction Code (NCC).

An independent compliance review also failed to detect this issue, allowing the error to pass unchecked into construction. The result was a collapse that could have had far more severe consequences had the roof been fully loaded or occupied.

Key Learnings for the Industry

This case underscores several important lessons for engineers, designers, project managers, and certifiers:

1. Design Responsibility Is a WHS Duty

Under the WHS Act, designers have a duty to ensure their work is safe not just in its intended use, but during construction. This means bolts, connections, and base plates must be designed for real-world loads โ€” including wind uplift, combined shear and tension, and concrete breakout limits per NCC and relevant Australian Standards.

2. Review Procedures Must Be Robust โ€” and Followed

Having a documented review procedure is not enough if it isnโ€™t rigorously applied. Independent verification and internal peer review are critical to catching design errors before they reach site.

3. Certification Is Not a Rubber Stamp

Independent certifiers play a key role in safeguarding public safety. They must actively verify that designs meet compliance, rather than simply sign off on documentation.

4. Time Pressures Can Compromise Safety

Compressed project timelines were noted as a factor in missed opportunities to catch the error. Project teams must resist the temptation to shortcut review steps when schedules are tight โ€” safety must remain non-negotiable.

5. Documentation & Traceability Protect Everyone

Maintaining calculation records, checklists, and review signoffs creates a clear audit trail. This helps demonstrate due diligence if something goes wrong.

Infographic titled โ€˜Lessons From a Landmark Caseโ€™ displayed on a clipboard. It highlights key learnings from a structural failure case: design compliance, safety standards, bolts failure, and adequate specifications. At the centre is a simple line drawing of a collapsed structure, with arrows pointing to four labelled boxes describing the importance of regulatory compliance, workplace safety standards, anchor bolt failures, and using suitable components to meet project requirements

Why This Matters

The collapse at Angaston Football Club was a relatively small incident with minor injuries โ€” but it could easily have been catastrophic. By learning from cases like this, the industry can improve its processes and prevent future failures.

As professionals, our role is to design for safety, verify rigorously, and document clearly. Doing so protects workers, end-users, and our own organisations.

Legal & Ethical Considerations

This post is intended as a learning resource, not as an allocation of blame. The case referenced is a matter of public record through SafeWork SA and SAET decisions, and all commentary here focuses on general principles of safe design and compliance.

We recommend that other practitioners review their own QA and certification procedures in light of this case to ensure compliance with the National Construction Code and WHS obligations.

The Future of Smelting & Steelmaking:

Trends Shaping a Greener, Smarter Industry


Steel has been the backbone of industrial progress for over 150 years. It is the invisible framework behind our skyscrapers, bridges, transport systems, and modern cities. But the industry that gave us the Industrial Revolution is now facing one of the greatest transitions in its history. The combined pressures of climate change, regulatory scrutiny, fluctuating energy costs, and global trade realignments are forcing steelmakers to rethink how steel is made, used, and traded.

Recent news reports show a fascinating picture: a sector in the middle of transformation, experimenting with new technologies like hydrogen-based direct reduction, while still relying on traditional blast furnace smelting to meet soaring demand. In this article, we explore the future direction of the smelting and steelmaking industry, what challenges lie ahead, and where the biggest opportunities are likely to emerge.


The Push for Green Steel

Hydrogen & Direct Reduced Iron (DRI): A Pathway to Decarbonization

Hydrogen-based steel production remains the single most promising pathway for deep decarbonization in the steel sector. Instead of using metallurgical coal and coke to chemically reduce iron ore, hydrogen can be used to produce direct reduced iron (DRI) that can then be melted in an electric arc furnace (EAF). This dramatically cuts COโ‚‚ emissions, especially if the hydrogen is produced using renewable energy.

Projects like Salzgitterโ€™s Salcos program in Germany are leading the way. Salzgitter has been developing one of the most ambitious hydrogen-based steel transformation roadmaps in Europe, gradually phasing in hydrogen reduction units and retiring carbon-intensive blast furnaces. Similarly, Australiaโ€™s NeoSmelt initiative, backed by Rio Tinto and ARENA, is exploring a combination of DRI and electric smelting furnaces to create a pathway that works for Australian ore quality and energy markets.

But this transition is anything but smooth. Salzgitter has recently delayed later stages of its program, citing economic and regulatory headwinds, such as the high cost of hydrogen, uncertain carbon pricing, and the slow rollout of renewable energy infrastructure. This highlights a hard truth: the green transition will not be instant or cheap. The next decade will likely be defined by pilot projects, incremental scale-ups, and careful balancing between economic viability and climate commitments.


The Coal Paradox

Even as green steel makes headlines, metallurgical coal is seeing a surprising resurgence. Demand for coal-based blast furnace production remains robust, especially in China and India, where domestic infrastructure spending continues to grow. In fact, recent research from the Global Energy Monitor shows that coal-based capacity is still expanding, even as global climate targets call for steep reductions in emissions.

This paradox points to the transitional nature of the current era. For the foreseeable future, the world will be living in a dual-track steel economy: one track relying on traditional blast furnaces and coke ovens to meet near-term demand, and another experimenting with hydrogen, electric smelting, and alternative reduction technologies.

For businesses, this means they cannot simply abandon existing capacity overnight. Instead, expect to see retrofit investments to improve the efficiency of blast furnaces, capture more waste heat, and install carbon capture and storage (CCS) where feasible. This โ€œcleaner coalโ€ approach will act as a bridge until low-carbon technologies can compete at scale on cost and availability.


Regional Shifts & Strategic Investments

Australiaโ€™s Green Steel Ambitions

Australia is emerging as a key player in the global conversation on sustainable steelmaking. The country has vast high-grade iron ore resources, growing renewable energy capacity, and a strategic interest in maintaining domestic steelmaking capability.

  • BlueScopeโ€™s $1.15B blast furnace reline at Port Kembla is one of the largest industrial projects in the nationโ€™s history, designed to keep steel production secure for another 20 years. This investment shows that Australia is taking a pragmatic approach โ€” continuing to support blast furnace technology while planning for a green future.
  • The NeoSmelt project, which just secured nearly $20M in government funding, is a potential game-changer. It will explore how to combine renewable-powered hydrogen and electric furnaces to make a commercial-scale green steel process that works with Australian ore.
  • The potential takeover of Whyalla Steelworks by a consortium led by BlueScope could turn the plant into a testbed for low-emissions ironmaking, providing a national blueprint for decarbonizing heavy industry.

Global Trade & Policy Realignment

Meanwhile, trade policy is also shaping the future. The EU and U.S. have resumed talks to revisit steel and aluminium tariffs, with a focus on creating carbon-based trade measures. If implemented, this could reward producers who adopt low-carbon technologies while penalizing those that rely on high-emission processes. For global producers, this will accelerate investment in low-emissions capacity to stay competitive in export markets.


Innovation Beyond Furnaces

The transformation of steelmaking is not just about switching fuels โ€” itโ€™s about reimagining the entire production system.

  • Modular, low-emission smelting plants like those being developed in Western Australia by Metal Logic allow companies to build capacity closer to demand centers, reduce transport emissions, and scale production up or down as needed.
  • Digital twins and AI-driven process control are making smelting more efficient. By modeling every step of the steelmaking process, producers can optimize energy use, reduce material losses, and increase yield โ€” all of which improve profitability and lower emissions simultaneously.
  • Circular economy practices, such as increased use of scrap steel in EAFs, are becoming a central strategy. Recycling steel uses a fraction of the energy required to make virgin steel and fits neatly into the industryโ€™s sustainability narrative.

This convergence of physical and digital innovation will likely create a new generation of steel plants that are smaller, smarter, and cleaner than their 20th-century predecessors.


Where the Industry is Headed

Looking ahead, the future of smelting and steelmaking will be defined by hybridization, regulation, and resilience:

  • Hybrid production systems will dominate for at least the next decade. Expect blast furnaces to operate alongside hydrogen-based DRI units and electric smelters as companies transition gradually.
  • Stricter carbon regulations will push companies to adopt low-carbon pathways faster than market forces alone would dictate. Carbon border adjustment mechanisms (CBAMs) will effectively tax โ€œdirty steelโ€ in major economies, making investment in green capacity a competitive necessity.
  • Domestic capability building will remain critical. The COVID-era supply chain crises reminded governments why domestic production matters. Expect to see policies that support keeping steelmaking onshore, even if that requires subsidies or preferential procurement.
  • Collaborative innovation will become the norm. Mining giants, energy producers, and technology firms are already forming alliances to solve the โ€œgreen steel puzzle.โ€ This cross-industry collaboration will unlock new efficiencies and accelerate commercialization.

Final Thoughts

The smelting and steelmaking industry is standing at the crossroads of history. The coming years will test its ability to balance sustainability with profitability, scale with flexibility, and tradition with innovation.

Companies that embrace this challenge โ€” investing in low-carbon technology, digital transformation, and strategic partnerships โ€” will not just survive the coming disruption but thrive as leaders in a new, greener industrial age. Steel may be one of the oldest materials in human civilization, but its future is being forged right now, and it has never been more exciting.

Why 3D Point Clouds + Expert Modelers Are a Game-Changer for Your Projects

Infographic illustrating the 3D project data workflow, showing LiDAR scanners and drones capturing millions of data points, a designer modelling on a computer, and project teams validating accurate 3D data, highlighting benefits such as speed, accuracy, cost savings and project success.

Level Up your 3D Scans

In todayโ€™s world, accuracy and efficiency can make or break a project. Whether youโ€™re working in architecture, construction, engineering, or product design, you need reliable data โ€” and you need it fast. Thatโ€™s where 3D point clouds come in.

But thereโ€™s an important catch: not all scans are created equal. The difference between an average scan and a great one often comes down to the person behind the scanner. Having someone who understands 3D modeling take the scans can dramatically improve your projectโ€™s accuracy, reliability, and overall success.

Letโ€™s break down why.


The Power of 3D Point Clouds

Point clouds are essentially millions of tiny data points that capture the shape of an object, room, or entire site. Together, they create a highly detailed digital snapshot of the real world.

Hereโ€™s why this matters:

  • Precision you can trust โ€“ Point clouds deliver incredibly detailed measurements, capturing even the smallest curves and angles.
  • Nothing gets missed โ€“ Multiple scan angles ensure a full, 360ยฐ view of your site or object.
  • Speed and efficiency โ€“ What used to take hours (or days) with manual measurements can be captured in minutes.
  • Built-in context โ€“ Youโ€™re not just getting numbers; youโ€™re getting a complete digital environment to work inside.
  • Future-proof data โ€“ Once you have a scan, you have a permanent record of your space, ready to use months or years later.

From clash detection to as-built verification, point clouds save time, reduce errors, and make collaboration across teams smoother than ever.


Why the Person Taking the Scan Matters

While technology is powerful, experience is what makes the results reliable. Having a skilled 3D modeler operate the scanner can be the difference between a good project and a great one.

Hereโ€™s why an expert makes all the difference:

  • They know what matters โ€“ A modeler understands which details are critical for your project and ensures theyโ€™re captured.
  • Fewer gaps, fewer surprises โ€“ Experienced pros know how to plan scan positions to cover every angle and avoid blind spots.
  • Cleaner, more accurate data โ€“ They reduce common issues like noise, misalignment, or missing sections that can throw off your model.
  • Time saved, headaches avoided โ€“ No one wants to redo a scan halfway through a project. A professional ensures you get it right the first time.
  • Confidence from start to finish โ€“ When you know your model is accurate, you can move forward with design and construction decisions without second-guessing.

In short: a great scanner operator doesnโ€™t just deliver data โ€” they deliver peace of mind.


The Bottom Line

3D point clouds are already transforming how projects are planned and delivered. But pairing them with an experienced 3D modeler takes things to the next level.

Youโ€™ll get better data, faster turnarounds, and a far lower risk of costly mistakes. And when your goal is to deliver projects on time, on budget, and with zero surprises, thatโ€™s an edge you canโ€™t afford to miss.

Chute Design in the Mining Industry

Infographic showing Hamilton By Designโ€™s engineering workflow, including millimetre-accurate LiDAR reality capture, material-flow simulation, optimised chute designs, and safer, more efficient production outcomes. Two workers in PPE highlight reliable design and longer liner life, with icons representing time, cost and quality benefits.

Getting Coal, Hard Rock, and ROM Material Flow Right

Chute design is one of the most critical yet challenging aspects of mining and mineral processing. Whether you are handling coal, hard rock ore, or raw ROM material, chutes and transfer stations are the unsung workhorses of every operation. When designed well, they guide material smoothly, minimise wear, and keep conveyors running. When designed poorly, they cause blockages, spillage, excessive dust, and expensive downtime.

Modern chute design has moved far beyond rules of thumb and back-of-the-envelope sketches. Today, successful projects rely on accurate as-built data, particle trajectory analysis, and advanced Discrete Element Method (DEM) simulation to predict, visualise, and optimise material flow before steel is cut. In this article, we explore why these tools have become essential, how they work together, and where software can โ€” and cannot โ€” replace engineering judgement.


Illustration showing common problems with poorly designed material-handling chutes. A chute discharges material onto a conveyor while issues are highlighted around it: unpredictable material flow, material spillage, maintenance challenges, high wear, blockages, and dust and noise. Warning icons for downtime and cost appear on the conveyor, and workers are shown dealing with the resulting hazards and maintenance tasks.

The Challenge of Chute Design

Coal and hard rock have very different flow behaviours. Coal tends to be softer, generate more dust, and be prone to degradation, while hard rock is more abrasive and can damage chutes if impact angles are not controlled. ROM material adds another level of complexity โ€” oversize lumps, fines, and moisture variation can cause hang-ups or uneven flow.

Chute design must balance several competing objectives:

  • Control the trajectory of incoming material to reduce impact and wear
  • Prevent blockages by maintaining flowability, even with wet or sticky ore
  • Manage dust and noise to meet environmental and workplace health requirements
  • Fit within existing plant space with minimal modification to conveyors and structures
  • Be maintainable โ€” liners must be accessible and replaceable without excessive downtime

Meeting all these goals without accurate data and simulation is like trying to design in the dark.

Speech bubbles highlight issues such as โ€œOutdated drawings donโ€™t tell the full storyโ€ and โ€œModifications rarely get documented.โ€ The scan data is shown being visualised on a laptop, with notes describing full coverage of conveyors, walkways, and services. Benefits listed along the bottom include faster data collection, fewer site revisits, safer shutdowns, accurate starting point for design simulation, and safer outcomes that ensure designs fit first time.

Capturing the Truth with 3D Scanning

The first step in any successful chute project is to understand the as-built environment. In many operations, drawings are outdated, modifications have been made over the years, and the real plant geometry may differ from what is on paper. Manual measurement is slow, risky, and often incomplete.

This is where 3D laser scanning changes the game. Using tripod-mounted or mobile LiDAR scanners, engineers can capture the entire transfer station, conveyors, surrounding steelwork, and services in a matter of hours. The result is a dense point cloud with millimetre accuracy that reflects the true state of the plant.

From here, the point cloud is cleaned and converted into a 3D model. This ensures the new chute design will not clash with existing structures, and that all clearances are known. It also allows maintenance teams to plan safe access for liner change-outs and other work, as the scanned model can be navigated virtually to check reach and access envelopes.


Understanding Particle Trajectory

Once the physical environment is known, the next challenge is to understand the particle trajectory โ€” the path that material takes as it leaves the head pulley or previous transfer point.

Trajectory depends on belt speed, material characteristics, and discharge angle. For coal, fine particles may spread wider than the coarse fraction, while for ROM ore, large lumps may follow a ballistic path that needs to be controlled to prevent impact damage.

Accurately modelling trajectory ensures that the material enters the chute in the right location and direction. This minimises impact forces, reducing wear on liners and avoiding the โ€œsplashโ€ that creates spillage and dust. It also prevents the material from hitting obstructions or dead zones that could lead to build-up and blockages.

Modern software can plot the trajectory curve for different loading conditions, providing a starting point for chute geometry. This is a critical step โ€” if the trajectory is wrong, the chute design will be fighting against the natural path of the material.


The Power of DEM Simulation

While trajectory gives a first approximation, real-world flow is far more complex. This is where Discrete Element Method (DEM) simulation comes into play. DEM models represent bulk material as thousands (or millions) of individual particles, each following the laws of motion and interacting with one another.

When a DEM simulation is run on a chute design:

  • You can visualise material flow in 3D, watching how particles accelerate, collide, and settle
  • Impact zones become clear, showing where liners will wear fastest
  • Areas of turbulence, dust generation, or segregation are identified
  • Build-up points and potential blockages are predicted

This allows engineers to experiment with chute geometry before fabrication. Angles can be changed, ledges removed, and flow-aiding features like hood and spoon profiles or rock-boxes optimised to achieve smooth, controlled flow.

For coal, DEM can help ensure material lands gently on the receiving belt, reducing degradation and dust. For hard rock, it can ensure that the energy of impact is directed onto replaceable wear liners rather than structural plate. For ROM ore, it can help prevent oversize lumps from wedging in critical locations.

๐Ÿ–ฅ Strengths and Limitations of Software

Modern DEM packages are powerful, but they are not magic. Software such as EDEM, Rocky DEM, or Altairโ€™s tools can simulate a wide range of materials and geometries, but they rely on good input data and skilled interpretation.

Key strengths include:

  • Ability to model complex, 3D geometries and particle interactions
  • High visualisation power for communicating designs to stakeholders
  • Capability to run multiple scenarios (different feed rates, moisture contents, ore types) quickly

However, there are limitations:

  • Material calibration is critical. If the particle shape, friction, and cohesion parameters are wrong, the results will not match reality.
  • Computational cost can be high โ€” detailed simulations of large chutes with millions of particles may take hours or days to run.
  • Engineering judgement is still needed. Software will not tell you the โ€œbestโ€ design โ€” it will only show how a proposed design behaves under given conditions.

Thatโ€™s why DEM is best used as part of a holistic workflow that includes field data, trajectory analysis, and experienced design review.


From Model to Real-World Results

When the simulation results are validated and optimised, the design can be finalised. The point cloud model ensures the chute will fit in the available space, and the DEM results give confidence that it will perform as intended.

This means fabrication can proceed with fewer changes and less risk. During shutdown, installation goes smoothly, because clashes have already been resolved in the digital model. Once commissioned, the chute delivers predictable flow, less spillage, and longer liner life.


Why It Matters More Than Ever

Todayโ€™s mining operations face tighter production schedules, stricter environmental compliance, and increasing cost pressures. Downtime is expensive, and the margin for error is shrinking.

By combining 3D scanning, trajectory modelling, and DEM simulation, operations can move from reactive problem-solving to proactive improvement. Instead of waiting for blockages or failures, they can design out the problems before they occur, saving both time and money.
