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
Open cast: Highwall mining is used to mine coal from underneath the final highwall, when the strip limit is reached due to economic reasons or surface conditions; Contour mining: In a mountainous area, the Cat highwall mining system can follow a coal seam along the side of the hill

Highwall mining is used in open-cut coal mining operations with a continuous mining machine and a modular conveyor train being remotely driven into the exposed coal seam at the base of an open-cut highwall. The extraction process creates multiple tunnels that can extend over 500m, with supporting coal pillars left in between.

many routine highwall mining situations. However, exceptions are frequently encountered. The case histories are used to illustrate many common exceptions, namely 1) the presence of old auger holes, 2) highwall mining under back-stacked spoil and finally, 3) closely-spaced multiple seam mining. Auger and highwall mining are safe and productive

operator, with 20 years of mining experience, was fatally injured when a highwa ll he was working near collapsed. The excavator was being used to load rock trucks. The operator's cab was positioned on the highwall side when the accident occurred.
Apr 29, 2016· Almost all the coal is produced from open cut mines in Indonesia. As a consequence of open cut mine application, a great deal of coal is left out in the highwalls of the mined-out pits. Highwall mining systems can be used to recover this coal. The use of highwall mining systems has increasingly come into play in the US and Australia. However, it is not common in Indonesia. Moreover, Indonesia
