Hazardous Gases: Methane • MineARC Systems

Nov 12, 2019 NIOSH states, methane monitors are required by law to be mounted on machinery and throughout a mine to alert personnel of any increase in the gases levels while extracting coal. Routine monitoring of methane is required at the working face of mine, due to the higher propensity for ignition.

CDC Mining Topic Methane Detection and Monitoring

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.

The most common gas to cause underground mine explosions is methane. Methane is a colourless, odourless, highly flammable, and highly explosive noxious gas that occurs naturally and gets trapped in coal layers. Methane becomes combustible at levels between 5% and 14% in the air. All it takes is a naked flame or a spark from a machine to cause
