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
Mining of coal is one of the oldest industrial operation. The mining method selected for exploitation is determined mainly by the characteristics of the coal deposit and the limits imposed by ...
Jan 27, 2014· The most common mining method is longwall mining which is largely automated using a selfadvancing coal shearer including hydraulic roof supports 150250m wide 3m high extract panels roof collapses as machine withdrawals. This is the safest way to mine coal and shale as it requires no blasting in a potentially explosive environment.
FIGURE F1 Schematic of a roomandpillar coal mine section. SOURCE: Arch Coal, Inc., 2012. FIGURE F2 Details of the longwall face. SOURCE: EIA, 1995. There are several variations of each method. However, ever since the introduction of continuous miners in the late 1940s, roomandpillar continuous mining has been gaining ground over conventional roomandpillar mining.

The booklet discusses the environmental aspects of metal mining and illustrates the ways science and technology assist in preventing or reducing environmental impacts; Coal Mining and Transportation (Webpage), Energy Information Administration Webpage describing different methods used for mining, processing, and transporting coal.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine – a pit, and the ...

Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step bystep mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.
Mining Techniques Equipment. Over the past 250 hundred years, the coal mining industry has witnessed significant changes to both its mining techniques and the equipment used throughout the mining process. Changes evolved through a need to make a safer underground environment for the thousands of miners employed in Cape Breton''s coal industry.
IMPROVING SAFETY AT SMALL UNDERGROUND MINES Proceedings: Bureau of Mines Technology Transfer Seminar Compiled by Robert H. peters'' ABSTRACT This Bureau of Mines report identifies the types of serious accidents that occur most frequently at small underground coal mines and describes the strategies that could help prevent these accidents.
The function of the mining engineer is to apply knowledge of pertinent scientific theory, engineering fundamentals, and improved technology to recover natural resources. Mining is a worldwide activity involving the extraction of nonmetallics, metal ores of all kinds, and solid fuel and energy sources such as coal and nuclear materials.

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...
