Dangerous incident | SInNot 2018/00202
Summary: While travelling through a traffic light area a person transport vehicle made contact with a high voltage plug.
Recommendations to industry: Mine operators should review how planned tasks capture all potential hazards when assessing a task. Consideration should also be given to the expertise of those involving in assessing the task.
Dangerous incident | SInNot 2018/00197
Summary: While a contract driller was drilling a pit pattern in an open cut coal mine, a flammable gas ignited within the drill hole. The fire propagated from the hole to the front hydraulic system and partially burnt and damaged the cab. The operator activated the automatic fire suppression system, which was ineffective because of the flammable gas burning in the hole. An emergency was initiated and two water carts extinguished the fire.
Recommendations to industry: Mine operators should review any previous industry incidents, not just site incidents associated with a piece of plant, machinery or task. This should also be considered when developing a lifecycle management plan for plant or machinery.
Dangerous incident | SInNot 2018/00195
Summary: A coalburst was reported on a longwall between shields 92-107. About 50 tonnes of coal was ejected. The shearer was cutting from the maingate to the tailgate. The majority of the ejected material occurred where the shearer was positioned, over onto the shield pontoons.
One operator was injured and taken to hospital. The operator was given three stitches to the left hand.
Recommendations to industry: Mine operators should review:
- if they have considered the potential change in risk when there is a change from normal production tasks
- that their current trigger action response plans (TARPs) achieve a proactive result.
Serious injury | SInNot 2018/00194
Summary: An operator was sprayed with hydraulic oil on the left forearm from a bolter inner rig. The oil release originated from an O-ring that failed with no apparent mechanical damage to the fitting or components.
Recommendations to industry:
- Mine operators should be competent to work on hydraulic systems including assembly of fittings and sealing components.
- Mechanical protection and safeguards should be used to mitigate the risk of release of hydraulic fluid pressure should also be used as far as reasonably practicable.
