Strip mining is a form of surface mining that is primarily used for coal excavation. The rock and dirt covering the ore is removed one strip at a time. Once the ore has been taken from the first strip, a second strip is cut next to it, and the waste from the second strip is used to back fill the first. This goes on until the ore is exhausted, and then the waste from the first strip is used to ...
Coal Hollow Surface Mine Process Description The Coal Hollow Mine will be a surface coal mining operation. The coal sizing portion of the plant will be similar to a sand and gravel operation, with crushing/sizing and stockpiling of material. The coal mining will occur in sequential pits, with backfilling and reclamation immediately following coal removal from each pit. Coal will be transported ...

Surface mining removes the earth and rock that lies above the coal or mineral seam and places the overburden off to one side as spoil. The exposed ore is removed and preliminary processing is done on site or the ore is taken by truck to processing plants. After the mining operations are complete, the surface can be recontoured, restored, and reclaimed.
· Surface mining and deep underground mining are the two main methods of mining coal. Depth, density, and thickness of the coal seam are the factors that are taken into account while selecting the mining method for coal extraction. However, many coals extracted by using these two methods need washing in a coal preparation plant. Surface mining: The mining technique is used when the coal .
