emissions, whereas for active mines, such a process mines the gas before the coal is extracted. CBM well Vents can also be drilled directly down into coal seams adjacent to the coal face. coal seams are stimulated and, after removing any water, methane can be extracted from the coal seam. This is essentially a direct mining process

The main impacts of surface mining are, in gen-eral, massive disturbances of large areas of land and possible disruption of surface and ground-water patterns. In some surface mines, the gen-eration of acid mine drainage (AMD) is a major problem. Other significant impacts include fugi-tive dust and disposal of overburden and waste rock.

Get PriceLarger emissions of greenhouse gases lead to higher concentrations in the atmosphere. Greenhouse gas concentrations are measured in parts per million, parts per billion, and even parts per trillion. One part per million is equivalent to one drop of water diluted into about 13 gallons of liquid (roughly the fuel tank of a compact car).

Methane is a highly explosive gas trapped within coal layers. Mechanical errors from improperly used or malfunctioning mining equipment (such as safety lamps or electrical equipment) or the use of improper explosives underground can trigger methane and initiate consecutive coal dust explosions.

Mines, specifically in this case coal mines. Studies since the 1970's have identified methane emissions from coal mines. An active coal mine will emit as much methane to the atmosphere as a good "fracked" natural gas well OPENED to the atmosphere. In the US alone there are 600 active coal mines, there are 500,000 abandoned mines.

instance, methane released by a mine in the production of coal could be measured and divided amongst the quantity of coal produced. This could then be added to, inter alia, the emissions from oil burned in the coal's transport, and the carbon dioxide released in the coal's combustion. 3.
