  • MINING METHODS ,authorSTREAM

    Coal is mined by two main methods : Underground or 'deep' mining Surface or 'open-cut' mining The choice of method is largely determined by the geology of the coal deposit, in particular the depth of the seam below the surface. The majority of the world's coal reserves are recoverable by underground mining.

    • Until the early 1970's, the majority of coal production in the U.S. was via underground mining methods. • Advancements in technology (primarily hydraulics and explosives) and expansion of mining activities in the west (particularly in the PRB), have shifted mining trends from underground to surface production over the past 40 years. Year

  • 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

    The estimated coal production in South Africa in the year 2009 was 250.6 Mt. About 60.5 Mt of coal was exported, while 184.7 Mt was consumed domestically, with 64% of it being used for power generation. South Africa’s mining giant, Anglo American produced nearly 59.2 Mt of coal in 2009, despite the economic slump.
