Slow leak - approx 600l ofhydraulic fluid lost to ground. Operator notaware of failure until low oil level alarmdisplayed.1 Bates South Pit – EX2500 digger workingin tight area made contact with losematerial which subsequently broke awayfalling and breaking fitting on hydraulic oiltanker.1 Service truck fuelling water cart 21182,fuel tank overflowed spilling approx 300ltsof diesel onto ground – Fuel cap missingfrom tank – Not identified prior to fuelling1 Spillage of approx 200L of AmmoniumNitrate Emulsion (ANE)1 40L of ANFO emulsion released toground at reloading facility during reload.Pumping started before seals fitted toACTION TAKENArea of contamination was bunded and excavated anddeposited at RL100. Continue ongoing maintenanceand pre-shift checks to ensure integrity of hose(s) andfittings.Digger was shutdown, stopping release andcontamination was contained to localised area. Area ofcontamination was excavated and hauled to RL130dump. Operation of digger in soft conditions causingdamage to track tension return hose in swivel area,identified as contributing factor in hose failure. Continuewith scheduled ongoing maintenance and inspections.Operator was notified by personnel of oil leak,immediately shut machine down, reported andsubsequent containment and clean-up actions / disposalwas undertaken. Operator(s) to consider workingenvironments, particularly tight environments andenvironments where changes throughout the course ofwork occur.Contaminated soil removed from area and disposed offinto Rug Dump.
