Mining Infrastructure Engineering | 3D LiDAR Scanning, Chute Design & AS 4991
Mining Infrastructure Engineering: From 3D LiDAR Scanning to Safer, Better-Performing Plant
Mining infrastructure rarely operates exactly as it appears on the original drawings.
Processing plants evolve. Conveyors are modified. Platforms are extended. Chutes wear. Equipment is replaced. Lifting arrangements are developed to support maintenance activities, and structural steel is frequently altered during successive shutdowns.
Over time, the difference between the documented plant and the actual plant can become significant.
For engineers working on brownfield mining projects, this creates an important challenge:
How do you design new equipment confidently when the existing conditions may not be fully known?
A practical solution is to combine three engineering disciplines:
Accurate 3D LiDAR reality capture
Engineering design and verification
Detailed mechanical and materials-handling design
Together, these capabilities can provide a much stronger foundation for mining infrastructure upgrades, shutdown projects and plant modifications.
Start With the Plant That Actually Exists
Traditional brownfield engineering often begins with legacy drawings, photographs, manual measurements and previous project documentation.
These sources remain useful, but they should not automatically be assumed to represent current site conditions.
Mining and mineral-processing facilities are continually modified throughout their operating lives.
A conveyor may have been repositioned.
A chute may have received additional liners.
Pipework may have been rerouted.
Access platforms may have changed.
New structural members may have been added during previous projects.
Even relatively small changes can affect the installation of new equipment.
This is where 3D LiDAR scanning in Perth and Western Australia can provide significant value.
Rather than capturing a limited number of individual dimensions, terrestrial LiDAR scanning records millions of measurement points throughout the surrounding environment.
The resulting registered point cloud creates a detailed three-dimensional representation of the plant as it exists at the time of scanning.
For mining infrastructure projects, this can include:
conveyors;
transfer stations;
crushers;
screens;
bins and hoppers;
structural steel;
platforms and stairs;
pipework;
mechanical equipment;
lifting areas;
maintenance access;
processing equipment; and
surrounding plant interfaces.
The objective is not simply to produce an impressive 3D image.
The objective is to create engineering information that can be measured and used.
Why Reality Capture Matters in Western Australian Mining
Western Australian mining projects present particular engineering challenges.
Many assets are located hundreds or thousands of kilometres from the engineering teams responsible for designing modifications.
A project may be designed from Perth while the physical equipment is located in the Pilbara, Goldfields or another remote mining region.
Repeated site visits can therefore be expensive and difficult to coordinate.
A comprehensive LiDAR dataset allows engineers and designers to effectively return to the captured area digitally.
Dimensions can be checked.
Clearances can be reviewed.
Equipment locations can be examined.
Structural interfaces can be investigated.
Proposed equipment can also be modelled relative to existing plant.
Hamilton By Design's 3D LiDAR scanning services across Perth and Western Australia are intended to support these types of engineering, mining, mineral-processing and brownfield applications.
Typical point-cloud outputs can include formats such as E57, RCP, RCS, LAS, XYZ, PTS and PTX, allowing captured information to move into downstream engineering and CAD workflows.
From Point Cloud to Engineering Model
Reality capture is most useful when it forms the beginning of the engineering process rather than the end of it.
A practical workflow might look like:
Site inspection → LiDAR scanning → point-cloud registration → 3D CAD modelling → engineering analysis → design development → fabrication drawings → installation
The point cloud establishes the physical constraints.
Engineering judgement then determines what should be changed.
This distinction is important.
A scanner can identify where something is.
It cannot automatically decide:
whether a structure is adequate;
whether a lifting beam is compliant;
whether a chute trajectory is appropriate;
whether maintenance access is sufficient;
whether a proposed modification is practical to fabricate; or
whether equipment will perform reliably after installation.
Those questions require engineering.
Design Verification for Mining Lifting Equipment
Mining operations rely heavily on lifting devices.
Maintenance activities can involve removal and installation of motors, gearboxes, pumps, screens, crusher components, conveyor equipment, liners and many other heavy components.
Special-purpose lifting equipment may therefore include:
lifting beams;
spreader beams;
lifting frames;
lifting lugs;
equipment-specific lifting fixtures;
fabricated lifting attachments; and
maintenance lifting devices.
Producing the fabrication drawing, however, is only part of the engineering process.
Hamilton By Design's article on Design Verification Under AS 4991 highlights an important distinction between simply fabricating a lifting device and demonstrating that its engineering design has been appropriately considered and documented.
Engineering considerations can include matters such as:
design loads;
load paths;
structural capacity;
limit states;
weld design;
material selection;
connection details;
design calculations;
documentation; and
verification requirements.
This becomes particularly important for customised lifting devices developed for maintenance tasks.
Where 3D Scanning and Lifting Engineering Meet
Reality capture can also help when designing lifting arrangements around existing mining equipment.
Consider replacing a large gearbox inside an operating processing plant.
The engineer may need to understand:
available crane or monorail access;
surrounding structural steel;
nearby pipework;
removal paths;
equipment centre of gravity;
available lifting height;
maintenance clearances; and
connection locations.
A point cloud can document much of the surrounding geometry before the lifting arrangement is developed.
The lifting device itself can then be designed around the real physical environment rather than an assumed one.
This does not replace engineering verification.
Instead, accurate reality capture provides better input information for engineering verification.
Chute Design: Geometry Is Only Half the Problem
Few components demonstrate the interaction between geometry and engineering performance better than a mining transfer chute.
A chute may appear relatively simple on a fabrication drawing.
In operation, however, it must manage a continuously changing stream of bulk material.
Depending on the application, this could include:
coal;
iron ore;
copper ore;
gold-bearing ore;
crushed rock;
ROM material;
concentrate; or
other bulk solids.
Poor transfer behaviour can contribute to:
excessive wear;
blockages;
spillage;
dust generation;
belt mistracking;
impact damage;
maintenance problems; and
production downtime.
For this reason, chute design for mining should consider more than the external shape of the steelwork.
The behaviour of the material passing through the chute matters just as much. Hamilton By Design's chute-design approach considers accurate existing-condition information alongside material trajectory analysis and Discrete Element Method simulation where appropriate.
Understanding the Existing Transfer Station
Before redesigning an existing chute, engineers need to understand the surrounding plant.
This might include:
feed conveyor geometry;
head pulley position;
receiving belt location;
belt width;
belt speed;
structural steel;
existing chute geometry;
liner arrangement;
surrounding services;
skirt systems;
inspection doors;
maintenance platforms; and
available installation space.
Trying to reconstruct all of this using a tape measure and a notebook can be difficult.
A terrestrial LiDAR scan can capture the transfer station as an interconnected three-dimensional environment.
That point cloud can then provide the reference geometry for subsequent CAD development.
From Measured Geometry to Material Flow
Once the existing geometry has been established, the next question becomes:
What is the material actually doing inside the chute?
This is where engineering analysis becomes important.
Depending on the project, designers may examine:
material trajectory;
impact angle;
velocity;
flow direction;
loading position on the receiving belt;
potential dead zones;
wear locations;
material properties;
liner positioning; and
potential blockage zones.
Discrete Element Method — commonly called DEM — can provide another engineering tool for investigating these conditions.
Rather than relying solely on intuition, a virtual representation of particles moving through the proposed geometry can be studied before the chute is fabricated.
DEM is not a substitute for practical engineering judgement, operating knowledge or good site information.
Used appropriately, however, it can provide engineers with additional information for comparing design alternatives.
An Integrated Mining Infrastructure Workflow
The real opportunity comes from combining these technologies rather than treating them as separate services.
Consider a brownfield conveyor transfer station scheduled for modification during an upcoming shutdown.
Stage 1 — Capture
The existing plant is documented using engineering-grade 3D LiDAR scanning.
The scan records the conveyor structure, chute, platforms, equipment and surrounding interfaces.
Stage 2 — Model
The registered point cloud is brought into the engineering environment.
Relevant components and interfaces can then be reconstructed as CAD geometry.
Stage 3 — Investigate
Existing chute performance is reviewed.
Areas of wear, impact, spillage or restricted flow can be considered alongside operational information from site personnel.
Stage 4 — Design
A revised mining chute design can be developed within the constraints captured from the existing plant.
Material trajectories and DEM analysis may be incorporated where they provide useful design insight.
Stage 5 — Maintenance Planning
If specialised lifting fixtures are required to install or maintain the equipment, the lifting arrangement can also be incorporated into the engineering model.
Stage 6 — Verification
Appropriate engineering calculations and AS 4991 design verification can then support lifting-device documentation and compliance requirements.
Stage 7 — Fabrication and Installation
Fabrication drawings can be produced from geometry developed around measured existing conditions.
The objective is straightforward:
reduce surprises when the new steel reaches site.
Why This Matters During Mining Shutdowns
Shutdowns compress weeks or months of planning into a relatively short execution period.
Once the plant stops, delays become expensive.
Problems such as these are therefore particularly undesirable:
“The steel doesn't fit.”
“There's a pipe where the new chute needs to go.”
“The lifting beam doesn't clear the structure.”
“The maintenance platform interferes with the removal path.”
“The existing conveyor isn't where the old drawing shows it.”
Many brownfield installation problems originate much earlier than the shutdown itself.
They begin with incomplete information.
Capturing the plant accurately before detailed design begins can therefore reduce one important source of project uncertainty.
Engineering With a Tradesman's Understanding of the Plant
Digital engineering is powerful, but mining infrastructure still exists in the physical world.
Someone has to fabricate it.
Someone has to weld it.
Someone has to install it.
Someone has to maintain it.
And eventually, someone has to remove it again.
Good mining engineering therefore requires more than producing an accurate CAD model.
Design decisions should consider:
fabrication;
welding;
transport;
lifting;
installation;
access;
maintainability;
liner replacement;
shutdown sequencing;
inspection; and
future equipment removal.
That practical understanding is particularly important in brownfield environments where even technically correct designs can become difficult to install if surrounding conditions have not been properly considered.
SolidWorks and Digital Engineering for Mining Infrastructure
For mechanical engineering projects, the point cloud can ultimately become part of a broader 3D engineering environment.
Rather than designing an isolated component, engineers can develop equipment within the context of the existing facility.
That creates opportunities for:
interference checking;
equipment arrangement studies;
maintenance-envelope assessment;
fabrication modelling;
structural and mechanical detailing;
lifting studies;
design reviews;
visual communication with stakeholders; and
preparation of manufacturing drawings.
The result is a digital workflow that links the existing physical plant with the proposed engineering solution.
Three Questions Before Starting a Brownfield Mining Project
Before commencing the next plant modification, it can be useful to ask three simple questions.
1. Do we actually know what is there?
If drawings are incomplete or the plant has been repeatedly modified, reality capture may provide a stronger starting point.

2. Has the engineered equipment been properly verified?
For specialised lifting devices, design documentation and verification need to be considered as part of the engineering process.
Explore: Design Verification Under AS 4991
3. Have we considered how the material will actually behave?
For conveyors and transfer stations, successful chute design requires consideration of the bulk material as well as the fabricated geometry.

Better Mining Infrastructure Starts With Better Information
Mining infrastructure engineering increasingly combines physical site experience with digital tools.
3D LiDAR scanning provides the measured reality.
CAD provides the design environment.
Engineering calculations provide the technical basis.
Design verification provides assurance.
Material-flow analysis provides insight into chute performance.
Practical experience connects these tools to fabrication, installation and maintenance.
For Western Australian mining operations in particular, where engineering teams may be separated from remote assets by significant distances, creating a reliable digital record of the existing plant can provide considerable value throughout the project lifecycle. Hamilton By Design supports LiDAR projects across Perth and regional WA, including mining and industrial locations where accurate existing-condition information is important for maintenance, capital works and plant upgrades.
Ultimately, the goal is not simply to produce more data or more complex models.
It is to make better engineering decisions before fabrication begins.
Frequently Asked Questions
Can 3D LiDAR scanning be used on existing mining plants?
Yes. LiDAR scanning is particularly useful for brownfield mining and mineral-processing facilities because it captures current plant geometry rather than relying solely on historical drawings.
What can be produced from a LiDAR scan?
Depending on the project, deliverables can include registered point clouds in formats such as E57, RCP, RCS, LAS and XYZ, together with downstream CAD models and drawings where required.
Why scan a chute or transfer station before redesigning it?
Scanning can document the relationship between conveyors, chutes, structural steel, platforms, equipment and surrounding services. This provides reliable existing geometry for the new design.
Can LiDAR scanning improve shutdown planning?
It can support shutdown planning by giving engineering teams a detailed digital representation of existing conditions before shutdown work begins, allowing spatial constraints and potential interfaces to be reviewed earlier.
What is DEM chute simulation?
Discrete Element Method simulation models the movement and interaction of particles through transfer equipment. It can help engineers investigate trajectories, impacts, wear zones and material-flow behaviour when developing chute designs.
Why is AS 4991 relevant to mining?
Mining and heavy-industry maintenance frequently uses purpose-designed lifting devices. Engineering calculations, verification, material selection, weld design and suitable documentation form important parts of the design and compliance process.
Can scanning, chute design and lifting engineering be combined on one project?
Yes. On a brownfield plant upgrade, scanning can establish existing conditions, chute engineering can address material handling, and lifting-device engineering can support installation and future maintenance requirements.
