Longwall mining is more efficient than room and pillar mining, but the equipment is more expensive. Surface Mining For extracting coal which lies close the surface, huge drag-line shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines.

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 ...
Western Kentucky represented, in the time period covered by this book from the 1950s-80s, the bulk of coal mining in North America. Attributed to in John Prine's famous song "Paradise," Muhlenberg County is home to Kentucky's first commercial coal mine named the McLean Drift Bank.

Coal mining has had many developments over the recent years, from the early days of men tunneling, digging and manually extracting the coal on carts, to large open cut and long wall mines. Mining at this scale requires the use of heavy equipment in many different forms.
Starting around 1900, mechanization was applied to this method. By 1940, some referred to longwall mining as "the conveyor method" of mining, after the most prominent piece of machinery involved. Unlike earlier longwall mining, the use of a conveyor belt parallel to the coal face forced the face to be developed along a straight line. The only other machinery used was an electric cutter to ...
Ventilation. Good quality air has to be provided for personnel to breath, to dilute both natural and introduced (e.g. diesel exhaust) gases, to dilute or carry away dust and to provide cooling for personnel and machinery.
Coal mines operated without electricity. Electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (Electricity was first introduced into Ohio's bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery.
