Dangerous incident | IncNot0040098
Underground coal mine
Principal mining hazard: Ground or strata failure

Summary: A roof fall, approximately six metres long, measuring the full width of the drive (5.4 metres) and two metres high, occurred in the main gate of an underground coal mine directly behind the continuous miner where the area was supported. Two fitters on a continuous miner noticed some flaking in the roof and immediately went outbye just prior to the fall of ground. The ground failure was sudden.

Comments to industry: Underground mines must have systems in place to ensure the correct installation of designed strata support. This includes requirements and frequency of encapsulation test, pull test, torque test on drill rigs and inspection of installation spacing. Once these requirements are determined mine operators must make compliance variations.

Dangerous incident | IncNot0040114
Open cut coal mine
|
|
|
Summary: The operator of a dump truck smelled smoke in the cabin, activated the emergency stop button and exited the truck. There was a loud bang and the truck began to roll away. The unmanned dump truck travelled approximately 30 metres in an arc before coming to a stop. Initial investigation indicates a loose wire has shorted out the 24 volt supply to the dump-brake switch, causing a fire behind the dash and ultimately causing the truck to move on the incline.

Comments to industry: When activating the emergency stop in a dump truck, plant operators should also ensure that the park brake is applied before exiting the vehicle.

Uncontrolled movement of loader
A front-end loader drove up a ramp on a stockpile. The loader was on a soft edge as he backed down, so he stopped immediately and asked for help. The operator had recently commenced employment at the site, had previous loader experience, and was signed off as competent on the loader after observation and training.
