Methane is a highly flammable gas that is commonly found in coal mines, and if left undetected, it can cause explosions and other dangerous incidents. The monitoring of methane levels in mines is done using specialized equipment, such as gas detectors and sampling devices. These devices are installed throughout the mine and are regularly checked and calibrated to ensure that they are providing accurate readings. If methane levels are detected to be above safe levels, miners are evacuated and the area is immediately ventilated to disperse the gas.
