Every drive.
Every stope.
As actually mined.

Walk the level, scan the void. What comes back is the shape that is really there — measured, sectioned and ready to put beside the design.

What we scan

Drives and stopes, from the same walk.

A development drive captured as a point cloud, the heading at one end and a junction at the other A drive. Captured end to end, with the heading and the junction in the same dataset.
A stope void captured as a point cloud, opening off the end of a level drive A stope. The void as mined, opening off the level — shape and extent, not the design outline.

The stope surface as a watertight mesh, green where the scan had returns behind it and amber where the reconstruction filled in a surface nothing was scanned from The void, closed. Green is surface with returns behind it. Amber is where the fit supplied a surface and nothing was scanned.

The honest part is the amber.

A watertight volume has to close, so the reconstruction fills whatever it cannot see — usually a brow the scanner never got round. Most software hands you the number and says nothing. This report colours the filled surface separately and states the split:

  • 2,748 m² measured — returns behind it
  • 116 m² filled in by the fit
  • 2,863 m² total surface

So when someone asks how much of the volume was actually seen, there is an answer: 96%.

What you get

Measured, not just captured.

Every plate below is an actual export, with its own figures on it.

Profile along chainage: cross-sectional area, width and height extent, clear width at the inscribed centreline, back height, and the largest circle that fits, plotted over twenty metres of drive Profile along chainage. 21 sections over 20 m — area 26.8 m² (20.8–33.5), largest inscribed circle 3.29–5.46 m.
Plan view of a drive coloured by height, with the setup stations marked along the centreline Plan. 23.5 M returns, 6 setups at 5 m.
Three cross-sections swept from the cloud at chainage 2, 10 and 19 metres, each labelled with area, width, back height and inscribed circle Cross-sections. 72 bearings per section, gaps left as gaps.

Gaps are left as gaps. Where the scan could not see a surface, the section shows a gap rather than a line drawn through it.

In colour

The drive as it looks, not just as it measures.

The cameras ride with the scanner, so the cloud can carry the rock's own colour. The camera here follows the scanner's own trajectory through the capture — nothing is animated for effect.

Useful when somebody needs to recognise a place rather than measure it: which bolt, which wet patch, which end of which drive.

The face

Found, then measured.

The end of the drive is detected from the capture itself — a density rise where the scan stops going forward — then a plane is fitted to it and the rock measured against that plane.

On the example beside: the face found 9.55 m past the last pose, plane fitted at 19.8° to the drive, roughness measured against a local plane over 12 cm.

The face of a drive: an orthophoto, a residual map showing where the rock sits off the fitted face plane, and a histogram of how rough the face is Orthophoto, residual off the fitted plane, and how rough the face is.
A 360 degree panorama taken at one setup station in the drive, showing the back, both walls and the floor A 360° panorama at every setup station.
The capture

A station every few metres, with pictures.

The walk becomes a set of survey stations along the drive, each one carrying a full panorama. So a question about the ground — what the back looked like at chainage 40, where the water was coming in — is answered by going and looking, not by going back underground.

  • One operator, walking
  • Stations placed at a stated spacing along the drive
  • Delivered as a structured multi-setup E57, panoramas embedded
Questions

Before you ask

Can you scan an active heading?

Need answer

How reliable is a stope volume?

Every volume is reported with the share of surface that actually had returns behind it. On the 120 NW stope that was 96% — so the figure is 7,950 m³ with 4% of the surface closed by the fit, stated rather than folded in. A volume without that split is a number you cannot check.

What do we receive?

Plan and profile along chainage, cross-sections at whatever interval you want, shotcrete coverage where it is wanted, the face measured against a fitted plane, and the capture itself as a structured multi-setup E57 with a 360° panorama at every station.

Can you compare the scan against our design?

Confirm

Where do you work?
