Underground mining requires equipment and manpower to operate under the earth surface. Subsurface atmosphere may be contaminated with poisonous gases that displace the necessary oxygen to support life; or flammable gases that may cause explosion. Therefore, it is necessary to develop technologies and find ways to accurately measure concentration levels of toxic and flammable gases levels in subsurface atmosphere for safety of underground coal mines. Each sensor has its own advantages and constraints, like some sensors are better for sensing toxic gases and some are better for combustible gas detection. The paper enumerates operating principle, working procedure and application of different types of sensors for monitoring toxic and flammable gases in hazardous areas.
