COAL EXTRACTION AND PROCESSING - WordPress

Subsurface coal mining is the second major stage in the process of coal extraction and processing wherein coal is removed from underneath the surface of the earth. During the mining stage, workers use powerful machines to drill into the earth and extract raw coal which can be refined during the processing stage.

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; (5) extracting the coal; (6) processing the

Coal Mining Processing Equipment Flow Chart Cases - JXSC

After removing the coal from the ground, the miners may send it to a preparation plant near the mining site. The plant cleans and processes coal to remove rocks, dirt, ash, sulfur, and other unwanted materials. This process increases the heating value of the coal.

Common Coal Mining and Processing Terms

Coal washing is a process designed to separate the coal particles based on size, density and shape. Achieved by allowing the coal to settle in the wash fluid. Continuous Mining Continuous Mining is an underground method of extracting coal. The process utilises a machine that is capable of handling the entire extraction process.

Common Coal Mining and Processing Terms

Run-of-the-mine is the raw mineral extracted from the mine before any processing. In coal mining, run-of-the-mine is the coal as it comes from the mine, not treated at a preparation plant. Slurry Pipeline (coal) A slurry pipeline is used for transporting a viscous mixture of coal and liquid medium (water). They can be used for short-haul-transport, such as from a port facility to a

Coal Mining and Production - MIGA

Shallow, flat coal deposits are mined by surface processes, which are generally less costly (per ton of coal) than underground mines of similar capacity. Strip mining is one of the most economical surface processes. Here removal of overburden and coal extraction proceed in parallel strips along the face of the coal deposit, with the spoil being deposited behind the

Coal - National Geographic Society

Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
