TL;DR: Moranbah sits at the centre of the Bowen Basin's metallurgical coal heartland, surrounded by some of the largest longwall and open-cut mines on earth — Anglo American's Moranbah North and Grosvenor, BMA's Goonyella Riverside, Peak Downs and Saraji. Surveyors in Moranbah work statutory mine plans, longwall horizon control, subsidence monitoring and coal handling plant alignment. Industrial Spatial Solutions delivers mechanical surveys, engineering surveys, UAV/drone surveys and 3D laser scanning to Moranbah operators on a FIFO and project basis.
Key takeaways
- Moranbah is a purpose-built coal town of roughly 8,000–10,000 people in the Isaac Regional Council area, which hosts 31 active coal mines — the densest concentration of metallurgical coal operations in Australia.
- Anglo American's Moranbah North and Grosvenor underground longwall mines sit within 20 kilometres of town, while BMA's Goonyella Riverside, Peak Downs and Saraji open-cut and underground complexes ring the district to the north and south.
- Longwall extraction at Moranbah North and Grosvenor induces controlled surface subsidence that must be tracked against prediction models, making deformation and subsidence monitoring a continuous, non-negotiable requirement under Queensland's resources safety legislation.
- Coal from the district moves via the Goonyella rail system to the Hay Point and Dalrymple Bay terminals near Mackay — the world's largest metallurgical coal export complex — so survey control runs from the longwall face all the way to the shiploader.
- Queensland faces Australia's most severe surveyor shortage, so specialist contractors who can mobilise FIFO and turn around statutory and mechanical survey deliverables inside a maintenance shut are critical to Moranbah operators.

Moranbah: a coal town surrounded by giants
Moranbah was built in 1971 to house the workforce for the Goonyella mine, and almost everything about the town still revolves around coal. Located roughly 150 kilometres south-west of Mackay on the Peak Downs Highway, it is the closest residential centre to one of the most productive clusters of metallurgical coal mines anywhere in the world. Where Mackay is the logistics and services hub, Moranbah is the town at the coalface — the place crews live, equipment is staged, and shutdowns are run from.
The surrounding Isaac Regional Council area accounts for the bulk of the Bowen Basin's coal output, with 31 active mines feeding the metallurgical (coking) coal that supplies steelmakers across Japan, South Korea, India and China. Queensland's resources sector contributes around $61.6 billion to the state economy and employs more than 78,000 people, and the Moranbah district is one of its single largest contributors. The town's population swells well beyond its resident base once FIFO and drive-in drive-out workforces are counted, reflecting just how much labour the surrounding mines draw.
For surveyors, the significance of Moranbah is the sheer density and variety of work concentrated in a small radius. Within an hour's drive you have deep underground longwall mines, vast open-cut pits, coal handling and preparation plants (CHPPs), rail loadout loops, overland conveyors, tailings and water storage facilities, and accommodation villages. Every one of those assets generates survey demand, and much of it is legally mandated.
Key point: Moranbah is unusual because underground longwall mining, large-scale open-cut operations and dense coal handling infrastructure all sit within the same district — frequently on the same lease. That concentration means an operator often needs every discipline of industrial surveying delivered to one site, on one schedule.
Mining and resources around Moranbah
The mines around Moranbah split into two broad camps: Anglo American's underground longwall operations to the north and BMA's predominantly open-cut and hybrid operations spread through the district. Each carries a distinct survey profile.
Anglo American — Moranbah North and Grosvenor
Anglo American operates Moranbah North and Grosvenor, two underground longwall mines immediately north of the town. Moranbah North was an early adopter of remote longwall shearer operation, and both mines run high-output longwall faces in the Goonyella Middle seam. Grosvenor returned to longwall production following its 2024 rebuild after the 2020 underground ignition event, which placed an even sharper focus on monitoring, ventilation infrastructure surveys and as-built verification.
Survey demands across these operations include:
- Longwall face alignment and horizon control — underground surveys track face position, seam horizon and extraction boundaries against the approved mine plan, with the data feeding directly into automation and short-interval planning.
- Surface subsidence monitoring — longwall extraction induces predictable surface subsidence. Monitoring networks of survey marks and prisms track ground movement to validate prediction models and manage impacts on land, watercourses and infrastructure.
- Ventilation and conveyor drift surveys — gas drainage, ventilation shafts and underground conveyor drifts require precise as-built capture and alignment, particularly after modification or reinstatement works.
BHP Mitsubishi Alliance (BMA)
BMA's Bowen Basin complex includes Goonyella Riverside, Peak Downs, Saraji, Broadmeadow and Caval Ridge — several of the largest metallurgical coal mines on the planet, collectively producing tens of millions of tonnes a year. Goonyella Riverside and Broadmeadow combine open-cut and underground operations, while Peak Downs and Saraji are major draglining open-cut mines.
| Operation | Owner | Type | Approx. annual output | Primary survey needs |
|---|---|---|---|---|
| Moranbah North | Anglo American | Underground longwall | ~5 Mt | Longwall horizon control, subsidence monitoring |
| Grosvenor | Anglo American | Underground longwall | ~4 Mt | Longwall alignment, ventilation as-built, surface monitoring |
| Goonyella Riverside | BMA | Open-cut + underground | ~15 Mt | Pit progression, CHPP alignment, haul road |
| Peak Downs | BMA | Open-cut (dragline) | ~12 Mt | Large-scale pit survey, dragline set-out |
| Saraji | BMA | Open-cut | ~10 Mt | Production survey, dump management |
| Caval Ridge | BMA | Open-cut | ~8 Mt | Volumetrics, infrastructure, reconciliation |
Open-cut operations of this scale require relentless survey support: pit and dump progression survey for short-term planning and reconciliation, blast pattern set-out, dragline and shovel positioning during walks and assembly, and rehabilitation survey as voids reach final landform. Underground sections add statutory mine plan maintenance and roadway alignment on top.
Coal from the district is railed via the Goonyella rail system — an Aurizon-operated network exceeding 500 kilometres — to the Hay Point and Dalrymple Bay coal terminals south of Mackay, which together form the world's largest metallurgical coal export facility with combined capacity above 180 million tonnes per annum. Survey control therefore extends from the longwall face through the CHPP and rail loadout to the stacker-reclaimers and shiploaders at port.
Surveying services ISS provides in Moranbah
ISS delivers the full range of industrial surveying disciplines to Moranbah operators, scoped around the realities of coal mining: live plants, statutory obligations, tight shutdown windows and demanding site access.
Mechanical surveys
Mechanical surveys are central to Moranbah CHPP and materials handling work. A single coal handling and preparation plant packs dozens of conveyors, crushers, screens, dense medium cyclones, centrifuges and flotation cells into a confined footprint. ISS provides crusher and mill alignment to control vibration and bearing wear, conveyor head and tail pulley alignment to eliminate belt drift, screen deck levelling to design slope, and vessel and tank positioning relative to feed and discharge points. Typical mechanical alignment tolerances are held to within 0.1–0.5 mm depending on the asset, well inside manufacturer specifications.
Engineering and civil surveys
Engineering surveys support the infrastructure that keeps a mine running — haul roads, rail loops, dams, workshops, conveyor structures and accommodation expansions. ISS establishes and maintains control networks, provides construction set-out for civil works and structural steel, and delivers conformance and as-built survey for handover. Survey marks are tied to MGA2020 to ensure deliverables are accepted across mine planning and statutory workflows without rework.
UAV/drone surveys
UAV/drone surveys are the fastest, safest way to capture Moranbah's open-cut environment. ISS flies stockpile volumetrics on raw, product and reject coal — typically accurate to within 1–2% by volume — for inventory and financial reporting, plus pit and dump progression mapping, rehabilitation monitoring against approved landform plans, and sediment dam and water management surveys. All flights are conducted under CASA Remote Operator Certificate (ReOC) authority by licensed remote pilots.
3D laser scanning
3D laser scanning captures geometry that traditional methods cannot measure efficiently. ISS scanners capture up to roughly 2 million points per second, producing dense point clouds for CHPP as-built modelling, retrofit and tie-in design, clash detection, structural deformation monitoring across scan epochs, and underground void and goaf-edge capture for geotechnical analysis. Point clouds are delivered scan-to-BIM or scan-to-CAD as required.
Key point: Drone and laser scanning deliver speed and safety, but they only reach engineering accuracy when tied to a precision survey control network. ISS provides both the control and the capture technology, rather than aerial imagery alone.
Methods and equipment for Bowen Basin conditions
The Bowen Basin throws hard conditions at survey equipment and crews: summer heat regularly exceeding 40°C, fine coal and overburden dust, wet-season access constraints, and the haze and vibration of live plant. ISS selects methods and instruments to suit, rather than forcing one technique onto every job.
For statutory and high-precision work, ISS uses survey-grade total stations achieving angular accuracy around 1 arc-second and GNSS receivers running RTK and network corrections tied to MGA2020 and AHD. Underground and confined-plant geometry is captured with terrestrial laser scanners; open-cut volumetrics and rehabilitation are flown with RTK/PPK-enabled UAVs to minimise ground control over hazardous terrain. Mechanical alignment relies on precision total stations and laser-based alignment tools to hold sub-millimetre tolerances on rotating and fixed equipment.
| Do | Don't |
|---|---|
| Establish a tied control network before any drone or scan capture so deliverables reach engineering accuracy | Rely on standalone drone imagery without ground control and call it a survey-grade volume |
| Schedule mechanical surveys to land before equipment is stripped during a shut and again before reassembly | Assume a survey crew can be mobilised mid-shut at no notice without inductions in place |
| Plan open-cut UAV flights around dust events, blasting windows and exclusion zones | Fly without current CASA authority, site approval and an active flight notification |
| Account for heat and dust by calibrating and shading instruments and capturing during stable conditions | Use standard calibration assumptions in 40°C-plus heat shimmer over dark coal surfaces |
Standards and compliance in Queensland
Mining survey work around Moranbah is governed by Queensland's resources safety and survey legislation, and ISS deliverables are produced to be accepted by operators and the regulator without reprocessing.
- Coal Mining Safety and Health Act 1999 and Regulation 2017 — establish the safety and health framework for coal mines, including the obligations that surround accurate mine plans, ground control and monitoring. Survey-based subsidence and deformation monitoring is a routine part of meeting these obligations.
- Mining and Quarrying Safety and Health Regulation — requires accurate mine plans, regular survey pickup and certified completion records for extraction activities; statutory mine plans must be maintained by competent mine survey personnel.
- Surveyors Act 2003 (Qld) and Surveyors Regulation — govern who may carry out cadastral and certain survey work in Queensland and the standards that apply.
- Geocentric Datum of Australia 2020 (GDA2020/MGA2020) and AHD — the spatial datums ISS ties all deliverables to, ensuring compatibility with mine planning systems and statutory plans.
- CASA Part 101 and Remote Operator Certificate — all UAV operations are conducted under current CASA authority, with licensed remote pilots, site approvals and flight notifications.
Key point: ISS field staff hold current Queensland coal mine inductions, including self-contained self-rescuer (SCSR) and gas testing competencies for underground entry, and work under each site's safety and health management system. Deliverables are issued in the formats your planning and asset teams already use.
Why operators choose ISS in Moranbah
Industrial Spatial Solutions services Moranbah through FIFO and drive-in mobilisation coordinated from Mackay and Brisbane, structured around the operational rhythm of Bowen Basin coal:
- FIFO and project mobilisation — crews are mobilised to align with maintenance shuts, longwall moves and project milestones, with inductions and travel arranged ahead of the window.
- Shutdown turnaround — CHPP and plant shuts run on 48–72 hour cycles for major overhauls. ISS plans survey to land before equipment is stripped and again before reassembly, because every hour of shut downtime carries real cost.
- Underground-certified surveyors — field staff hold current Queensland underground coal certifications and site-specific inductions for the major Moranbah operations.
- Data integration — survey delivered in DWG, DXF, 12d Model, Surpac, Deswik, LandXML or point-cloud formats compatible with your mine planning and asset management systems.
Queensland's surveyor shortage is the most acute in the country, and the state's resources pipeline and infrastructure programme — through to the 2032 Brisbane Olympics — are all competing for the same shrinking pool of professionals. For Moranbah operators that means longer lead times and higher project risk when relying on generalist firms. ISS provides specialist industrial survey capacity built specifically for coal.
Frequently asked questions
How quickly can ISS mobilise surveyors to Moranbah?
ISS mobilises to Moranbah on a FIFO and drive-in basis from Mackay and Brisbane, scheduled around your maintenance shut, longwall move or project milestone. For planned work we lock in crews, inductions and travel ahead of the window; for urgent requirements during a shut we move as fast as site induction and access approvals allow. Where site inductions are already current, mobilisation is substantially faster.
What survey accuracy can ISS achieve at Moranbah mines?
It depends on the discipline. Mechanical alignment is held to sub-millimetre and 0.1–0.5 mm tolerances on rotating and fixed equipment. Total station control achieves angular accuracy around 1 arc-second. Laser scanning produces millimetre-level point clouds, and drone volumetrics typically land within 1–2% by volume. All work is tied to MGA2020 and AHD and produced to be accepted in statutory and planning workflows.
Is ISS certified to work on Moranbah underground coal mines?
Yes. ISS field staff hold current Queensland coal mine inductions, including self-contained self-rescuer (SCSR) and gas testing competencies required for underground entry, and work under each site's safety and health management system. We hold or obtain site-specific inductions for the major Moranbah operations before mobilising.
Which mines and assets around Moranbah does ISS cover?
ISS services the full Moranbah district — Anglo American's Moranbah North and Grosvenor, BMA's Goonyella Riverside, Peak Downs, Saraji, Broadmeadow and Caval Ridge, and surrounding mines, CHPPs, rail loadouts and infrastructure. We also support work further across the Isaac region at Dysart, Middlemount, Glenden, Coppabella and Nebo, and follow the coal chain through to the Hay Point and Dalrymple Bay terminals.
Can ISS survey during a CHPP shutdown or longwall move?
Yes. Shutdowns and longwall moves are core ISS work. For a CHPP shut we plan survey to capture as-built and alignment data before equipment is stripped and verify positioning before reassembly. For longwall moves we support equipment set-out and as-built capture so the face is recovered and reinstalled to plan, minimising the time the face is offline.
