2021-5-8 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; (5) extracting the coal; (6) processing the coal if necessary; and (7) decommissioning the mine

Coal is extracted by two principal methods, of which there are many variants: surface mining or subsurface mining. Surface mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams that are close to the Earth’s surface (figure \(\PageIndex{a}\)). Strip mining is a type of surface mining in which overburden is sequentially removed from each stretch (strip) of land. Once overburden is removed from the first strip, coal

2018-3-25 The different types of surface mining that can be used are: 1. Strip mining 2. Auger Mining 3. Open-pit mining 4. Mountain removal mining The second fundamental method of extracting coal is underground mining. This technique is used when the coal is buried deep inside the earth. The machines used for this type of coal extraction can excavate at depths of more than thousand feet. The coal

2021-5-8 The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2 ...

Mining is required to supply shale to the retorts of aboveground processes. The majority of oil shale mining is expected to be by the underground room-and-pillar method. Surface mining (i.e., open pit mining) may also be used to supply material for surface retorts and may be appropriate for up to 15 to 20% of the oil shale resources.

Usually coal from more than one source is produced at the same time to enable a proper coal blend designed to meet customer specifications. The underground mines utilize the room-and pillar mining method. The mining activities include development and panel preparation followed by de-pillaring mining.
