4 Coal Mining and Processing Coal: Research and

The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine

The third stage of the coalification process is bituminous coal. As per the course of the process, the carbon content of this type of coal is higher than the lower levels at around 45 to 86 percent. The heat value has also increased to between 10,500 and 15,500 BTU per pound.

What Are the Four Stages in Coal Formation?

Aug 04, 2015 Bituminous coal is used as an energy source in many parts of the world. The final stage of coal production is the anthracite stage. During this stage, soft coal becomes hard coal. It takes on a certain luster and is formed due to intense pressure and high temperatures. Anthracite produces little smoke and is the coal most people are familiar with.

Most underground coal is mined by the room and pillar method, where by rooms are cut into the coal bed leaving a series of pillars, or columns of coal, to help support the mine roof and control the flow of air.Generally, rooms are 2,000 feet wide and the pillars up to 300 feet wide. At least 60 feet of coal was left between an underground mine and the surface, if not the surface had a higher

Appendix E: Coal Mining and Processing Methods Coal

In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the
