12/03/2020 · 4. Open cast mining. Also known as open pit mining, this is a method of surface mining where a large pit is made in the ground, and the coal is mined directly from that pit. This is a great method to use for a shallow coal seam and it is extremely productive. Of all the types of mining, this is one of the safest processes.
Coal Extraction and Processing is a mineral removal and refinement process in which coal (black or brownishblack sedimentary rock composed mostly of carbon and hydrocarbons that contain energy that is released when burned) is removed from the Earth and treated for further use.
A loading mechanism to pick up cut coal and deliver it into the central part of the machine A conveying system, usually a chain conveyor running in a steel trough from front to rear of the miner A rear jib section capable of a degree of vertical and horizontal movement to enable the coal to be delivered into a transport or loaded at a desired ...

Here is a picture of a coal miner from 1814, when the Industrial Revolution was gathering pace. In the background, there is a steampowered locomotive, used to transport the coal in waggons along rails, and steampowered mine machinery, designed to help the miners bring the coal to the surface and to pump out water from the mine.
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 ...
Coal Washing. 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.
