The New South Wales Resources Regulator has released a document detailing a range of geotechnical failures in high walls, low walls and dumps.
The regulator said in its document (see link below) that a range incidents have been reported recently where people and equipment have been exposed to significant health and safety risks as a result of high walls, low walls and dumps failing.
The Regulator has advised mine owners that a range of control measures should be undertaken.
- Burying the boom | Incident highlights need for effective ground control
- Highwall collapse investigation report
- Excavator slips over edge of highwall | Operator escapes 20m fall
One of these measure includes that the controls include the thorough inspections are completed on all high walls, low-walls and dumps by open cut examiners and supervisors, prior to starting, and during mining operations, with the results of inspections recorded and communicated at pre-start meetings.
