Underground Mine Ventilation Technical Aspects of Mining

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

Coal mining Underground mining Britannica

Coal mining Coal mining Underground mining: In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities

Guidance about underground air quality and ventilation

The manager of an underground mine must ensure that a plan of the ventilation system at the mine is kept at the mine that shows the direction, course and volume of air currents, and the position of all air doors, stoppings, fans, regulators and ventilating devices, in the mine. It is important to understand the influence of following factors in
