Analysis Of Common Problems In Coal Mine Machine In Production

Coal is a common energy source in the steel industry to extract iron from iron ore, and in the cement production process. The four main types of coal are lignite, sub bituminous, bituminous, and anthracite. Each type has varying amounts of hydrogen, oxygen, nitrogen, sulphur, and carbon, and as a result they have different uses.

    The slope mine may go down for hundreds of feet but they are often sloping enough that a motor may be used for hauling the coal. In a shaft mine the men as well as the coal are hauled up and down in a sort of elevator. A Drift mine is one that starts from the side of a mountain and extends straight back on somewhat of a level.

    There are three different mining methods that are commonly used in underground mines in South Africa. The most common technique is the ‘bord and pillar’ method, which accounts for just under half of total coal production (SACRM, 2011). This method is ideal for relatively shallow deposits where overlying rock pressure is low.
