Opencast Mining an overview | ScienceDirect Topics
Coal is mined either by surface methods (opencut or opencast mining) or by underground techniques In surface mining, all of the rock from the ground surface to the top of the seam (material referred to as overburden) is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use ( Figure 11 )Environment Impact Assessment of Coal Mining Open cast mine has significant impact on land as compared to underground mine 1) Land Around 4 ha of land is damaged for every million tons of coal mined by from ledo mines Stream water sample D/S of the mines Ph 361 328 Cadmium 74 05 Chromium 455 73 Lead 4846 1098 Arsenic 226 601ledo open cast mine restaurantlegargantuafr
