Dangerous incident | IncNot0039650
Open cut coal mine
|
|
|
Summary: During commissioning of a new water line, the end cap was being undone in order to remove air build up when it ejected under pressure. It travelled approximately 25 metres and hit nearby infrastructure. A worker was using a socket and ratchet on the end cap bolts and was working from an elevated work platform about five metres from the ground at the time. The worker was not injured.

Comments to industry: Mine operators are reminded that effective isolation and energy dissipation is a critical risk control when working on pressurised fluid systems. Loosening bolts on an end cap is not a suitable method of dissipating air pressure in a water line. Appropriately rated valves should be used. Operators must ensure that pressurised fluid lines are isolated, with pressure dissipated prior to removing end caps. Refer to Safety Alert: SB12-03 Fluid power isolation failures

Dangerous incident | IncNot0039658
Underground coal mine
Principal mining hazard: Fire or explosion
|
|
|
Summary: Frictional ignition of methane gas occurred when the continuous miner cut through an ironstone lens.
|
|
|
Comments to industry: Appropriate procedures and TARP’s must be in place for when the risk changes, including changes in geology and the seam section being cut. Implementation and monitoring of the ventilation standards required to manage methane levels must be to a standard to minimise the risk. Ensure ventilation is installed and maintained to maximise ventilation quantities at the working face.

*While the majority of incidents are reported and recorded within a week of the event, some are notified outside this time period. The incidents in this report therefore have not necessarily occurred in a one week period. All newly recorded incidents, whatever the incident date, are reviewed by the Chief Inspector and senior staff each week and summarised in this report.
