Underground mine ventilation
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 source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself. ...
Coal Sludge Impoundments, West ia
Since the mid to late 1990s, the number and size of coal mines known as mountaintop removal mines increased dramatically in parts of ia, West ia, Pennsylvania, and Kentucky. The final step in processing this coal creates sludge that contains coal dust, sediment, and possibly heavy metals and chemicals. Mine operators contain the coal sludge in nearby valleys, behind huge earthen ...

Dense Medium Cyclone
· Magnetite size distribution. Cyclone inlet feed pressure. In most cases, the appropriate mediumtocoal ratio is determined by the coal preparation plant builder during the conceptual design phase of the project. Most dense medium cyclone circuits in the United States are operated with mediumtocoal ratios of 3:1 to 4:1, by volume.
Determining the influencing factors of preferential flow ...
Aug 31, 2020 · Ground fissures (GF), appearing in front of dumps, are one of the most obvious and harmful geological hazards in coal mining areas. Studying preferential flow and its influencing factors in the ground fissures of dumps may provide basic scientific support for understanding the rapid movement of water and vegetation restoration and reconstruction in mining areas.
Ventilation
Flow to different areas of the mine is regulated by constructing artificial restrictions in airways in the form of a stopping or doors with an opening usually of an adjustable size (by the use of adjustable louvers, sliding doors, etc), such restrictions being known as "regulators".

Coal Bed Methane | Energy Justice Network
Methane is loosely bound to coal held in place by the water in the coal deposits. The water contributes pressure that keeps methane gas attached to the coal. In CBM development, water is removed from the coal bed (by pumping), which decreases the pressure on the gas and allows it to detach from the coal and flow up the well. Figure I24.
