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 called a 'pit ...
But it's a different kind of pressure – environmental – that has changed the way we view coal as an energy source. We can help you find cleaner ways to extract coal by combining our project life cycle capabilities with mining technologies like smart power grids, electrification, and automation of processes and vehicles. Finding net-zero emissions is why we're still involved with coal.
manner in which to cost underground coal mining systems. With the use of a costing framework developed by the author incorpo-rating new thinking to eliminate the shortcomings identified in the traditional costing approach, a comparison of two types of underground coal mining systems, viz. continuous miner and longwall, is conducted.
By 1980, the U.S. mining community had reached a broad consensus regarding coal pillar design. The pillar load could be estimated from the tributary area theory, and the pillar strength from empirical formulas and laboratory coal strength testing. Then the growth of longwall mining required new thinking.
