The Labour Department investigation into the disaster found its most likely cause was a roof fall which drove methane into the mine. This ignited, causing the explosion which snuffed out the lives of twenty-nine workers.
Whenever methane levels reached 1.25 percent of the air in the mine equipment was supposed to shut down, but on November 19, 2010 the drilling rig’s methane sensor was faulty but the rig was kept operating. Inadequate monitoring of gas levels, said the Farish judgement, “contributed significantly” to the explosion. Indeed methane levels above 1.25% had occurred no less than 13 times in the 25 days leading up to the fatal explosion. In just the week before it, explosive levels of methane had been reached five times!
