    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 mechanical anchor bolt, the oldest design in use in underground coal mines, was the main roof support used in the coal mining industry due to the rapid rate of installation. Today, the fully grouted roof bolt is considered superior to the mechanical anchor bolt because of a better anchorage capacity and load transfer capability. Currently

    The development of rock engineering

    In 1960 a coal mine at Coalbrook in South Africa collapsed with the loss of 432 lives. This event was responsible for the initiation of an intensive research programme which resulted in major advances in the methods used for designing coal pillars (Salamon and Munro, 1967). The formal development of rock engineering or rock mechanics, as it was originally known, as an engineering discipline in

    Modular Coal Preparation Plants Schenck Process

    Modular Coal Preparation Plants (MCPP) prepares coal for a cleaner burning process, enhanced calorific value and cleaner emissions.
