Underground
mining

Restricted, complex workings where you can't stand back and watch a slope — movement is read by comparing scans over time, across kilometres of drives. DTG runs one of its largest monitoring programmes here.

The escalations that matter

Independent processing, review and escalation across DTG's underground convergence work — the throughput behind the numbers, and the discipline that turns it into the movements that matter.

You can’t stand back and look at an underground drive. Visibility is restricted, the geometry is complex, and movement isn’t watched on a live screen — it’s read by comparing one scan against the next, across kilometres of workings.
What's different here

That makes underground monitoring an interpretation problem as much as a measurement one: turning scan-over-scan comparison into a clear picture of what's actually moving.

The scale of it

Kilometre after kilometre of ground, read for movement.

Underground monitoring isn't one drive — it's a continuous programme spanning kilometre after kilometre of workings, every section compared over time. The scale is the point: sustaining a clear, consistent read across it.

Underground scan and deformation data processed, compared and reviewed for apparent movement, across active engagements.

How we monitor it

Reading movement across the workings.

Underground monitoring leans on spatial comparison and convergence — drawn from the best available sources and turned into one interpreted picture.

DTG's independence is the point: on your workings, what we recommend is driven by your ground and your data, not by any product. We integrate whatever's available — and because the value is in how we read it, new sources simply add to the picture.

Movement
Closure and deformation of drives over time — convergence monitoring
Spatial
Where movement has occurred and how much — scan-to-scan comparison
Deformation
Additional signals strengthening the read — radar & deformation data
Point
Targeted movement & support performance — extensometers & instruments
Where DTG's role ends

We interpret the movement. We don't replace the ground control team.

Being clear about the boundary is part of being trustworthy. DTG provides independent monitoring, processing, QA/QC and interpretation — strengthening the decision, not owning it.

We process, review and interpret convergence data, and escalate apparent movement.
We do not replace on-site geotechnical inspection or the mine's ground control function.
Ground support decisions and sign-off remain with the accountable engineers.
