Where mine monitoring projects come undone — and the fix.
Underground and on a pit floor, the failures are environmental and organisational far more than they are technical. These are the ones worth designing out before the first installation.
| What goes wrong | How you notice | The fix |
|---|---|---|
| Backbone shared with production systems | Safety-related data is unavailable during the events that matter most | Give safety-critical monitoring its own protected path and power, and prove it with a drill rather than a diagram |
| Equipment rated for the surface, used underground | Early failures, and a certification argument at the worst moment | Certification for the atmosphere is a gate, not a specification line — confirm it before anything else about the device |
| Coverage designed on a plan | Readings resolve to the wrong place, or stop where the workings advanced | Design to travel routes and re-survey as the mine develops; a static design ages with every metre of advance |
| Dust, water and vibration underestimated | Enclosures fill, connectors corrode, mounts loosen | Specify ingress protection for wash-down and blasting reality, and check mounts on the same cycle as the equipment they sit on |
| Data available but not owned by the section | Reports are produced and nothing changes underground | Route the alert to whoever can act on that shift, not only to a central dashboard |
| Contractor movements untracked | Reconciliation fails on exactly the people least familiar with the workings | Tie tag and access issuance to one process for employees and contractors alike |
| No drill against the physical record | Confidence in the system is assumed rather than tested | Run the reconciliation. A system that has never been checked against a roll-call is an untested assumption |
Two failures recur across commodities. Shared infrastructure is the first — monitoring that depends on the same power and network as production is unavailable in precisely the scenario it was installed for. Coverage that does not follow development is the second: workings advance, and a design that was correct at commissioning quietly stops describing where people actually are.
