MINE VENTILATION SYSTEMS

To maintain adequate ventilation through the life of a mine, careful advance ventilation planning is essential. Advance ventilation involves the consideration of two principal factors (1) the total volume flow rate of air required by the mine, and its satisfactory and economic distribution, and (2) the pressure required by the mine fan(s).

Coal Mining 101The Coal Seam

This is what the media always shows you — current surface mining operations — but they never show you the whole story. Surface coal mining techniques, which account for the majority of national coal production and roughly 42 percent of West Virginia's coal production, involve the mechanical removal of overlying native earth and rock or "overburden" to reach underlying coal

Underground mine ventilation Wikipedia

Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature.The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself.

Digging deeper Mining methods explainedAnglo American

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
