sensors used in coal mining

Mining | Edinburgh Sensors | Gas Detection & Monitoring Systems

The extraction of coal releases methane gas, which can mix with the air in a mine to form a hazard due to its flammability. Ventilation with fresh air from the surface is used to dilute the methane and reduce the risk of explosion. Monitoring of the methane content of ...
