Miner removed bolts thought to secure ""cap"" protecting an oil sensor threaded and bolted into a pressurized tank. The cap was then dislodged from silicone seal causing the release of pressure inside the tank and cap to strike the miner in the jaw. Other sensors had been accessed prior to this all located under bolted on protective covers not under pressure.
Freezing conditions over the weekend of December 17 & 18 created frozen and slippery ground. Shortly after the beginning of the shift, the miner was walking across the gravel mine, and slipped and fell on the frozen ground.
