Auger mining uses large-diameter drills mounted on m obile equipment to bore into a coal seam. Holes are horizontally drilled at regular intervals to depths of as much as 1,000 feet. As the cutting

Analysis and Application of Coal Seam Seismic Waves for ...

A coal seam is a dark brown or black banded deposit of coal that is visible within layers of rock. These seams are located underground and can be mined using either deep mining or strip mining techniques depending on their proximity to the surface. These seams undergo normal coal formation and serve as a conventional coal resource.The reserves of coal …

The main goal of the work was to determine whether a radar-based system could be used to detect coal-rock interfaces in order to establish a suitable mining horizon within the coal seam.

Underground coal

Longwall mining is an automated form of underground coal mining characterized by high recovery and extraction rates, feasible only in relatively flat-lying, thick, and uniform coal beds. A high-powered cutting machine (the shearer) is passed across the exposed face of coal, shearing away broken coal, which is continuously hauled away by a floor ...

Prediction of Residual Gas Content during Coal Roadway ...

The two major schools of coal mining are surface mining and underground mining. To qualify for surface mining, the coal seam must lie within 60 metres of the surface. The miners' job is to remove all of the 'overburden' – the cubic tons of rock, soil and trees above the coal seam -and expose the coal layer for extraction.

Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam. The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area.

Coal Mining Equipment for Sale | Thin Seam Coal Mining ...

It is not uncommon for underground coal mining to be conducted in the proximity of abandoned underground mines that are prone to accumulate water, methane or other toxic gases, and are often either poorly mapped or without good surface survey control. Mining into such abandoned voids poses a great safety risk to personnel, equipment, and production from inundation or toxic/explosive gas release.

Glossary of Mining Terms

Coal-Cutting Machine a machine for producing a cut in a seam of a mineral (usually coal) in underground operations. The cut facilitates the breaking of the remaining part of the layer by means of mechanical devices or explosives. Coal-cutting machines can operate in gently sloping, sloped, and steep seams. The first attempt to mechanize coal …
