28 reportable incidents, 3 summarised below

Dangerous incident | IncNot0042577

Underground metals mine
Summary: A tele-remote loader tripped off on low hydraulic oil. An operator went to investigate and found a small fire in the engine bay. The fire was extinguished with a hand-held extinguisher. A hydraulic hose failed and sprayed fluid onto hot engine components. 
Comments to industry: Hose management and protection is critical in preventing fires on mobile plant. Mine operators must have a system in place to identify defects and poor hose standards, assess the criticality and put controls in place to prevent a fire. Escape of fluid ignited by hot surfaces was identified as one of the top 2 causes of fires on mobile plant.

Dangerous incident | IncNot0042587

Open cut coal mine
Ground or strata failure
Summary: While a dump truck was being loaded at the toe of a highwall, material from in front of the presplit fell from the highwall and landed in the rear of the truck tray. The truck tray head-board lifted 2 to 3 metres and then free fell back down into the lowered position. The 2 operators in the cab were shaken and suffered minor injuries. The highwall where the failure occurred was not excavated back to the presplit wall, leaving potentially loose material hanging up on the wall. As the coal was removed below, the material in front of the presplit wall collapsed quickly. The loose material on the wall was not identified as part of the site’s geotechnical hazard reports.
Comments to industry: Mine operators must have safe systems of work in place to inspect highwalls. These inspections must consider conditions that may affect highwall stability. An assessment of the integrity of the highwall must be conducted before commencing work beneath the highwall. Loose material or overhanging rocks must be removed before any work commences or appropriate controls, such as an exclusion zone, put into place.

Safety Bulletin: SB20-01 Failure of highwalls, low walls and dumps

Dangerous incident | IncNot0042593

Underground coal mine
Summary: While lowering a roof support on a longwall recovery face, a fitter was hit in the chest by a release of fluid from a 63 mm return hose. The worker was about 1 metre from the point of failure.
Comments to industry: Mine operators must develop and adhere to strict inspection and maintenance standards to avoid hose failures because of damaged and aged hoses. When procedures specify the use of remotes and pendants, workers should not be entering no go zones to operate roof supports manually.

The driver of a tank truck was unloading fluid at a production facility. The driver was found unresponsive inside the pump box of the truck with their left arm sleeve entangled in the pump shaft. After an hour and 30 minutes of resuscitation efforts by workers and emergency response personnel, the worker was declared deceased from mechanical asphyxiation.

An excavator operator climbed up onto his digger to check the oil as part of his prestart checks. As he climbed down from the excavator holding the handrail, the worker missed the first step and fell to the ground, landing on his back. First aid was applied, and the worker did not sustain any serious injuries.

The bucket of an excavator working a double bench operation collided with the dovetail of a rear dump truck when swinging towards the truck tray. The excavator was on the lower 3.5 m high bench at the time of the incident. The impact caused a significant amount of movement to the truck and injury to the operator. The injured operator suffered a fracture to the C5 vertebrae, resulting in hospitalisation for a number of days.

WorkSafe is issuing a reminder about the importance of managing the risks associated with electrical energy while conducting surface mining and exploration activities.
An air core exploration drill rig was being set up to drill a hole located within a farmer's paddock. The operator had lowered the stabilising jack legs and was in the process of raising the mast when the winching cable made contact with a 12.7kV Single-Wire Earth Return (SWER) overhead powerline. The SWER line was approximately 7 m above ground level. The drill operator suffered a shock and immediately retreated from the rig at which point the overhead line was observed. Re-exposing the operator to the electrical hazard, the operator approached the rig and activated the rig's hydraulic levers with a 'shovel' to lower the mast.

*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.
