Machines Used in Coal Mining Career Trend

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. Surface mining may involve removing sections of hills or top layers of a flat surface area. The layers of rock and dirt covering the coal are reserved for until the coal is removed, at which ...

Mine Machines, Coal Cutting In the early days of using coal, loose coal would be gathered by hand where coal seams reach the Earth’s surface (outcrop). Hand tools such as picks were used to get the coal. As seams were mined underground, sharpened hand tools were the standard equipment and continued to be used in small mines until the 1950s. The earliest coal cutting machines used a

CHAPTER 11 Mining Technology

Surface Mining Techniques Surface mining of coal is characterized by the use of large, capital-intensive and effi-cient mining equipment. First, the overlying soil and rock layers (overburden) are re- moved. The coal is then fractured with explo-sives or machines, and loaded onto vehi-cles for haulage from the mine site. Finally, the disturbed land must be fully reclaimed. Principal ...

Coal Leader ::: Surface Mining

As a method of coal extraction, surface mining accounts for about 60% of total U.S. coal production of over 1 billion tons annually. It permits recovery of as much as 95% of the deposit due to the accessibility of the coal and the efficiency of massive high-tech equipment. At any given time, a large surface mine particularly in the western U.S. can be three miles long and a mile wide. The mine ...
