Laser Scanning — Rosebery

TL;DR: 3D laser scanning in Rosebery turns nearly 90 years of accreted, poorly documented underground and process infrastructure — MMG's concentrator, the headframes, conveyor galleries and legacy stopes — into dense, millimetre-accurate point clouds you can design and plan against. Industrial Spatial Solutions captures up to two million points per second with Leica scanners, registers to ICSM SP1 accuracy referenced to GDA2020 and AHD, and scopes every Bass Strait mobilisation completely so the data lands in one visit when your concentrator shutdown opens.

Key takeaways

• 3D laser scanning is the fastest, safest way to capture Rosebery's brownfield assets — the mill and flotation plant, headframes, bins, conveyor galleries and legacy voids — where original drawings are missing, superseded or simply wrong after extraction dating back to 1936.
• ISS delivers registered point clouds to roughly ±2 mm at 10 m, with E57, LAS/LAZ, RCP/RCS and PTX outputs that drop straight into Recap, Cyclone, Surpac, Deswik or your engineering CAD — the foundation for retrofit design, clash detection, stope stability assessment and as-built records.
• Real local applications run from the surface concentrator down to the workings: process-plant as-builts before a tie-in, void and stope scanning for geotechnical assessment of the legacy mine, and structural baselines on headframes and conveyor galleries.
• Scanning is non-contact and remote, so congested, live or hazardous areas — flotation rows, mill drives, crusher houses and unstable old voids — are captured without putting people in the line of fire or stopping the single concentrator the whole operation depends on.
• Tasmanian deliverables are referenced to GDA2020/AHD and ICSM SP1, accepted by Mineral Resources Tasmania and your engineers without rework; ISS plans every job around Bass Strait freight and the winding West Coast road so the scanner arrives on schedule.

3D laser scanning in Rosebery and the West Coast minerals province

Rosebery is a genuine mine town — around 700 people built on, and sustained by, a single deep underground operation in the steep, forested ranges beneath Mount Black and Mount Read. MMG's Rosebery mine has worked a volcanogenic massive sulphide orebody since 1936, yielding zinc, lead and copper concentrates with gold and silver credits, which puts it among the longest-lived underground operations anywhere in Australia. That longevity is exactly why 3D laser scanning Rosebery work is so valuable: nine decades of development, stoping, backfill and plant modification have left an asset base that almost never matches the drawings on file.

A scanner captures the asset as it actually is — every flange, bracket, beam, worn liner and irregular void wall — rather than as it was drawn decades ago, or never drawn at all. For the Rosebery concentrator, the headframes, the conveyor runs and the honeycomb of legacy stopes beside the active workings, that as-built point cloud becomes the single source of truth for retrofit design, clash detection, dimensional verification, stope stability assessment and asset records. It removes the guesswork — and the dangerous tape-and-clipboard pickups in live plant or near unstable ground — that otherwise precedes any modification.

This page covers how ISS delivers 3D laser scanning in Rosebery specifically: the local assets we scan, the method and equipment we use, the accuracy and deliverables you receive, and the standards and island logistics that govern the work. For the wider service overview see our 3D laser scanning guide, and for the full picture of survey support across the operation see surveyors Rosebery.

Local applications: what we scan at Rosebery

Because the entire operation feeds one on-site concentrator, scanning at Rosebery concentrates value on the assets that determine site-wide throughput — and on the legacy underground that has to be understood before anyone works near it. A single mobilisation can cover several assets, and the same point cloud often serves maintenance, engineering and geotechnical assessment at once.

Key scanning applications at Rosebery

Across these assets the common thread is the same: ageing, modified plant, missing or untrustworthy drawings, congested or live environments, and a need for survey-grade as-built data before any engineering or geotechnical work can start. Scanning the concentrator before a shutdown means new chutes, launders, platforms and pipework can be modelled into the cloud and clash-checked in the office rather than discovered on the gantry mid-outage. Scanning a legacy void captures geometry that no current drawing holds, feeding stope stability models directly. Scanning a decline against its design profile turns conformance from a tape-and-judgement exercise into a measured deviation report.

Key point: Rosebery runs on heavily modified assets accreted over nine decades, where the drawings cannot be trusted and the underground hides voids no plan records. 3D laser scanning establishes what is actually built — above ground and below — so design, fabrication, shutdown planning and stability assessment start from fact, not from an old red-line markup.

Method and equipment

ISS runs a disciplined scan workflow built for deep underground and congested process plant, not building facades. Every job is planned, captured, registered and delivered to a defined accuracy specification.

Site assessment and planning. Before scanning, we plan scanner positions, target placement and capture sequence to guarantee full coverage of cluttered plant and to control registration error. Underground and on live surface plant this includes the access, ground-support, isolation and exclusion-zone planning needed to scan around running mills, flotation rows and conveyors — and to keep crews clear of unstable legacy ground.

Data capture. We use Leica Geosystems scanners — the Leica RTC360 captures up to two million points per second with automatic target-free registration, ideal for the dense, dark, cluttered geometry of crusher houses, mill bays and underground drives. Each setup captures roughly 50–100 m of range at millimetre precision; phase-based scanning suits high-detail process plant and tight underground openings, while longer-range time-of-flight capture handles open stopes and surface structures.

Registration and processing. Individual scans are registered into a single unified point cloud in Leica Cyclone, tied to your underground and surface control and to GDA2020/AHD, with noise removed and registration residuals checked against the accuracy specification before sign-off. Underground, where GNSS is unavailable, registration relies on rigorous control transferred by total station and gyro-theodolite traverse.

Deliverable creation. From the registered cloud we produce exactly what your project needs: raw or cleaned point clouds (E57, LAS/LAZ, RCP/RCS, PTS/PTX), 2D plans, sections and elevations, mesh and solid CAD or BIM models, void meshes and volume reports, clash-detection reports, and deviation analysis comparing as-built against design or against an earlier scan epoch.

For new installs and overhauls, scanning pairs naturally with our mechanical alignment and laser-tracker work, and with drone surveys for stockpile and TSF-wide capture where scanning from the ground is impractical.

Accuracy, deliverables and cost

For most industrial work at Rosebery, ISS scanning delivers 3–5 mm accuracy at typical working distances, with registered point clouds repeatable to around ±2 mm at 10 m. Accuracy is driven by surface reflectivity, range, environmental conditions and — above all — registration quality, which is why target placement and overlap are planned rather than improvised. Dark mill steel, wet underground rock and the matt liners of a flotation circuit are exactly the conditions that separate a planned industrial scan from a quick walk-through.

Deliverables are matched to use. A maintenance team may need only a cleaned point cloud and key sections; an engineering retrofit needs a modelled deliverable and a clash report; a geotechnical assessment needs a void mesh and volume; a structural baseline needs deviation analysis against an earlier epoch. ISS scopes the output before mobilising so you are not paying for modelling you do not need.

As a guide, a contained structural or plant 3D scan with a registered point cloud generally runs AUD $4,000–$12,000 depending on size, access and the deliverable, inclusive of the Bass Strait crossing for equipment. Modelled CAD or BIM outputs, underground void campaigns and large multi-asset shutdown captures sit higher — a multi-day concentrator scan-and-model scope can reach AUD $20,000+ — while a single contained asset sits lower. Field data is typically returned within 24–48 hours, with scan registration usually complete within 3–7 days. Every Rosebery job is fixed-price quoted after scoping, with mobilisation to the West Coast set out transparently up front.

Standards and compliance in Tasmania

Mining at Rosebery operates under Tasmania's Mineral Resources Development Act 1995, administered by Mineral Resources Tasmania, alongside the Work Health and Safety Act 2012 (Tas) and its mines regulations, overseen by WorkSafe Tasmania. These frameworks require statutory mine survey plans maintained and certified by a registered mine surveyor, monitoring of structures and ground where there is a credible risk of failure, and accurate survey for tailings, rehabilitation and royalty purposes — and laser scan data underpins much of it, from void and stope capture to structural and embankment baselines.

ISS scan deliverables are referenced to GDA2020 and AHD and produced to ICSM SP1 accuracy standards, so they are accepted by Mineral Resources Tasmania and by your engineers without additional processing or rework. Where a job involves aerial capture to complement ground scanning — TSF surfaces, waste areas or steep portal ground — those flights are conducted under CASA CASR Part 101 by appropriately licensed remote pilots, and where crane or lifting structures fall within a scan scope they are assessed against AS 1418. Scanning instruments are calibrated to traceable ISO standards.

Key point: A point cloud is only as useful as its accuracy is defensible. ISS ties every Rosebery scan to underground and surface control and to GDA2020/AHD, registers to ICSM SP1, and documents residuals — so the data stands up for engineering design, statutory mine plans and stability assessment alike.

Why ISS for laser scanning in Rosebery

Tasmania's West Coast is a smaller, remote market, but it is high-value and technically demanding, and scanning a deep single-concentrator operation rewards a provider who plans around isolation rather than fighting it.

• Complete, scoped mobilisations — Rosebery is roughly 300 km from Hobart and around 130 km of winding road south of Burnie, with gear crossing Bass Strait by freight or ferry. We define every scan position, control point and deliverable before travelling, so the full scope is captured in one visit rather than discovered as missing after demobilisation.
• Underground and process-plant experience — Our teams scan congested, live and hazardous environments — mill drives, flotation rows, crusher houses, decline drives and unstable legacy voids — not just open structures, and they plan capture for dark, wet, cluttered conditions.
• Shutdown and turnaround focus — We schedule into your concentrator shutdown windows and work day and night shifts to compress scan time on the critical path of the one circuit the whole site depends on.
• Calibrated, current equipment — Leica RTC360-class scanners and Cyclone processing, regularly calibrated, with backup instrumentation carried to a remote site where the nearest replacement is across Bass Strait.
• Deliverables that fit your workflow — Point clouds, void meshes and models in the formats your engineers and geotechs actually use — AutoCAD, Civil 3D, Recap, Surpac, Deswik or 12d — scoped to the job so you do not pay for unnecessary modelling.

Frequently asked questions

Can ISS scan the Rosebery concentrator while it is operating?

In most cases, yes. 3D laser scanning is non-contact and captured from a distance, so with appropriate isolation, exclusion zones and access planning we can scan around running mills, flotation cells and conveyors without stopping the concentrator. Where a specific congested area must be captured statically and safely, we time it to a brief access window or to your shutdown — which is also when most retrofit-focused scanning is best done, so the cloud is ready for design before the next outage.

What accuracy and file formats will I receive from a Rosebery scan?

Registered point clouds are typically repeatable to around ±2 mm at 10 m, with 3–5 mm accuracy across most industrial work, all referenced to GDA2020/AHD and ICSM SP1. You receive whichever formats suit your software — E57, LAS/LAZ, RCP/RCS or PTS/PTX for the cloud — plus 2D drawings, mesh or CAD models, void meshes and volume reports, and clash or deviation analysis as your project requires.

Can ISS scan underground voids and stopes at Rosebery?

Yes. We scan decline and development drives for conformance against design, and legacy stopes and voids for geotechnical stability assessment and volume reconciliation, registering the data to underground control transferred by total station and gyro-theodolite traverse where GNSS cannot reach. The void mesh and volume outputs feed straight into stability models and reserve reconciliation alongside the same registered-cloud workflow we use on the surface plant.

How quickly can ISS mobilise a scanner to Rosebery?

Because Rosebery is on Tasmania's isolated West Coast and equipment crosses Bass Strait, we plan around freight and ferry timing rather than a same-day drive. For scheduled work we lock the scanner and crew to your shutdown window, with typical lead times of a few days to a week, and we scope completely up front so a single well-planned mobilisation delivers the full capture. For ongoing programmes we hold equipment in-region during the campaign so response is much faster.
