May 11, 2019 · Protective seam mining method is an effective way to eliminate the coal and gas outburst hazard. Auger mining (AM) is adopted to protective seam thinner than 1.0 m. The key of AM is to set intermediate coal pillar (ICP) because they have two functions: on the one hand, ICPs have to support the roof temporarily to avoid coal auger crushing; on the other hand, they have to be broken …
Coal mining - Wikipedia
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 ...
