· When the coal seam becomes exposed, it is drilled, fractured and the coal excavated for processing. Processing can be dependent on the cleanliness and quality of the coal mined. Opencut coal mining can be more costeffective and safer than underground coal mining methods. Typical recoveries of 90% of the coal seam are achieved through open cut coal mining methods. However .

As stated in the permit, wildlife habitat is the goal for postmining land use, and the primary objective of the reclamation plan is to encourage natural revegetation.
Coal mining is only a temporary use of land, so it is vital that mine rehabilitation takes place once operations have stopped. Detailed rehabilitation or reclamation plans are designed and approved, covering the period from the start of operations until well after mining has finished. Underground mining . Underground mining currently accounts for a bigger share of world coal production than ...
After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is loed at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal.

Mining, Processing, and Transporting Coal. Coal Mining. There are two ways to remove coal from the ground: surface mining and underground mining. Surface mining is used when a coal seam is relatively close to the surface, usually within 200 feet. The first step in surface mining is to remove and store the soil and rock covering the coal (called the "overburden"). Workers use a variety of heavy ...

Coal mine methane, less prevalent in the atmosphere than CO2, but 20 times as powerful as a greenhouse gas, forms during the geological formation of coal, and is released during the coal mining process. Most coal mine methane come from underground mines. While this methane is often captured and used as town fuel, industrial fuel, chemical feedstock and vehicle fuel, it's very rare that it ...
· During the process of mining the lower coal seam, the main concern is the coal pressure behavior law before and after the working face advances to the upper goaf boundary pillar.
