The U.S. Department of Labor’s Mine Safety and Health Administration released a summary of U.S. mining deaths that occurred during the third quarter of 2013. From July 1 to Sept. 30, there were nine mining fatalities in the United States. Five miners died in coal mining accidents and four in metal/nonmetal mining accidents. The number was two fewer than during the third quarter in 2012.
Two coal miners died in machinery accidents, and one each died in powered haulage, fall of roof or rib, and drowning accidents. Two metal/nonmetal miners died in powered haulage accidents, and one each died in machinery and falling/sliding material accidents.
Twenty-seven miners died in mining accidents in 2013 from Jan. 1 through Sept. 30, compared to 30 from Jan. 1, 2012, through Sept. 30, 2012.
“While the number of mining deaths was lower than in the same period last year, miners continue to die in accidents that could have been prevented, such as by using proximity detection equipment,” said Joseph A. Main, assistant secretary of labor for mine safety and health. On July 2, a continuous mining machine operator was killed when he was struck by a battery-powered coal hauler and pinned between the coal hauler and coal rib. Proximity detection systems can be programmed to send warning signals to alert miners to the presence of moving machinery and can stop the machinery before it strikes, pins or crushes a miner working in the vicinity. As of Sept. 30, 2013, 372 proximity detection systems had been installed on continuous mining machines, coal hauling machines and scoops in underground coal mines.
“In metal/nonmetal mining, fatalities continue to occur that could be prevented by using ‘lock out/tag out’ best practices,” said Main. “Two of the fatalities this quarter could have been avoided by: disconnecting the power, ensuring the miner on the job has locked the power source in the safe position and tagging to prevent the power from being re-energized.
“While actions undertaken by MSHA and the mining industry continue to move mine safety in the right direction, these deaths are a reminder that much more needs to be done to protect the nation’s miners and ensure they return home after every shift,” said Main.
