Underground Mine Ventilation | Technical

Coal mines are particularly susceptible to the presence of natural gases. These include toxic gases such as hydrogen sulphide (H 2 S) but the most significant are flammable gases, of which the most common is methane (CH 4). However, other flammable gases may occur. Furthermore, flammable gases may occur not only in coal mines but also in

MDG3 Fans in underground coal mines

Failure of any ventilation fan presents a major risk factor in the underground environment. At times, ventilation plant may be exposed to high levels of methane and potentially explosive atmospheres. Ventilation plant such as main fans, booster fans and auxiliary fans are crucial to providing a safe environment in an underground coal mine.
