carbon monoxide mining

Carbon Monoxide - Mine Safety and Health Administration - MSHA

Carbon monoxide (CO; CAS 630-08-0)) is a colorless, odorless, tasteless gas produced by the incomplete combustion of carbon-containing material such as coal, wood, paper, gasoline, and diesel fuel. Known to miners as white damp or the silent killer, CO constitutes a serious health hazard and exposure to it may even...

Modeling carbon monoxide spread in underground mine fires

May 5, 2016 ... Carbon monoxide (CO) poisoning is a leading cause of mine fire fatalities in underground mines. To reduce the hazard of CO poisoning in underground mines, it is important to accurately predict the spread of CO in underground mine entries when a fire occurs. This paper presents a study on modeling CO...
