The Coal Feeder is one among the long list of mining equipment with a broad range of choices to choose from depending on the application. The coal feeder is a feeding device which takes care of supplying raw material from one process to the other or solely for delivering the end product.
Open-pit mining. Some 53% of South Africa''s coal is produced from surface mining, via open-cast or open-pit mines. This is because the coal is less than 60 metres below the surface. Open-pit mines use draglines, as well as truck and shovel operations to extract coal. A dragline excavator uses a dragline to pull a bucket by a wire cable.
· During the process of mining, methane is released from the coal seam and surrounding rock strata. This can present a high risk of explosion at concentrations in air of 5 to 15 percent. In recent years, scientists have developed techniques to eliminate or dilute methane emissions before and during the mining process.

Coal mining is the process of getting coal out of the ground. It is part of the mining industry al is used as a resource for making electricity.. Extraction. Surface mining is done when the coal is near the surface. Coal miners remove the soil above the coal. The coal can then be removed without the coal miners having to go deep underground..
The readers of this tutorial are assumed to be associated with coal mining, and therefore familiar with coal mining operations and terminology. After reading this tutorial the reader should walk away with an adequate understanding of CT technologies that are being proposed for use in underground coal mines.
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 ...
