Ventilation Air Methane (VAM) Utilization Technologies

gas, is often present in underground coal seams and is a safety hazard to miners because it is explosive in concentrations ranging from 5 to 15 percent in air. Gassy underground coal mines employ large-scale ventilation systems to move fresh air into the mine. These systems dilute methane released into the mine workings as coal is extracted

5. FANS AND BLOWERS

Fans and blowers provide air for ventilation and industrial process requirements. Fans generate a pressure to move air (or gases) against a resistance caused by ducts, dampers, or other com-ponents in a fan system.

Assessing and managing spontaneous combustion of coal

coal in situ can also act as an ignition source which, together with elevated methane concentrations, will result in a mine explosion. Controlling explosions underground is therefore a combination of gas control (ventilation) as well as suppressio n of potential ignition incidents, including spontaneous combustion.
