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 is a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine.

This approach will compare the expected load of the pillar to its ultimate strength to determine its safety factor value. The main assumption of this approach is that, once the ultimate strength is overcome the pillar,GUIDELINES FOR THE INTEGRATED PLANNING AND DESIGN,The mine planning and design process for any new coal mining operation commences with the identification and analysis of specific market needs and requirements. These needs and requirements may be the result of increased export capacities, additional power station demand, shortages within specific sectors of the domestic coal market, or the replacement of older mines that have reached the
