Jul 23, 2020· Methane Detection and Monitoring What is the health and safety problem? The use of machine-mounted methane monitors is required by federal regulations to alert miners to the presence of potentially dangerous concentrations of methane while mining coal. The monitors must be permanently mounted on a mining machine to provide continuous readings of methane levels near a working face.
Several things make mining dangerous, chief among them the possible exposure to methane. This gas especially is dangerous because it cannot be seen or smelled, and appears naturally from the ground. When miners began to realize how dangerous methane was, they started exploring ways to detect it. CANARIES IN A COAL MINE
