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 is a 39pit39, andGet Price
For example, in coal and other soft rock mines, continuous miners break and load the mineral to eliminate drilling and blasting boring machines perform the same tasks in mediumhard rock. The cycle of operations in surface and underground mining differs primarily by the scale of the equipment.
Coal mining Coal mining Prospecting and exploration The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been discovered, considerable further work is
