An underground accident that resulted in a mine employee losing a finger brought a $30,000 fine and a $10,000 reparation order against East Otago mineral extracting company Oceana Gold.
The company had admitted breaching the Health and Safety in Employment Act by failing, as an employer, to take all practicable steps to ensure its employee, Johnstone Henry Lyle Palmer, was not exposed to hazards arising out of the use of a Sandvik DS420 cable bolter cement handling unit in his workplace on July 2, 2012.
Palmer had his hand in the bottom outlet of the machine's cement mixing bowl to clear out grout which had hardened during a delay in the grout being pumped between cable bolts and holes drilled in the roof of an underground roadway.
The water blaster which would normally have been used to clear the hardened grout was not working that day and a lower pressure hose was less effective.
Another employee had activated an interlock to stop the mixing paddles before he removed grout from the top of the bowl. But he inadvertently bumped the control switch while Palmer's left hand was in the dump valve at the base of the bowl. The dump valve was not protected by a guard and Palmer's hand was caught between the valve and the outlet.
