Coal mining: Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th
A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
Step 4: Once overburden is removed, backhoes load trucks with coal for transport to the mine stockyard and coal load-out system. Step 5: Using proprietary techniques established by Drummond, the coal is loaded into railcars directly from Drummond's stockyard.

Coal is weighed by a Kanawha batch weighing system that is certified by the Colorado Department of Agriculture Division of Weights and Measures. Sampling is performed by an ASTM approved three-stage automatic sampler. Coal is currently mined from the B seam. Coal seams at West Elk mine (B and E seams) contain over 150 million tons of ...
If the mine has open storage piles, the crushed coal passes through a coal stacker onto the pile. The piles, usually worked by bulldozers, are subject to wind erosion. From the storage area, the coal is conveyed to a train loading facility and is put into rail cars. At a captive mine, coal will go from the storage pile to the power plant.
Once the black coal loader was underground, he performed the laborious tasks of cutting, drilling, blasting, and loading coal. William Tams’s describes from his personal knowledge the job of a black coal miner. “The loader carried into the mine his picks, shovels, auger, tamping bar, fuse and a …
Miners had to be careful not to load any waste rock with the coal. The entire car full of coal could be rejected by the weighman if he determined that there was too much rock mixed with the coal and the miner would not be paid for the entire car load. Obviously this system was open to much abuse by the coal companies.

FUNDAMENTALS OF COAL MINE ROOF SUPPORT By Christopher Mark, Ph.D.,1 and Thomas M. Barczak2 ABSTRACT Roof supports can only be understood in conjunction with the rock structure that they support. The strength of the rock depends on geology, and the loads are applied primarily by the in situ and mining-induced stresses.
Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

It is intended as handbook for engineers who are new to the field of mining engineering, or for students who are entering the field with little prior knowledge.
Loading of coal cargoes ... Prior to loading coal it is important that the vessel has multi gas detectors on board capable for measuring oxygen (O 2), methane (CH 4), carbon monoxide (CO) and hydrogen sulphide (H 2 S). These gas detectors should have sufficient length on the inlet hose to reach all levels of the free space in the holds.
