term of water availability and quality). 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 the surface mining. For instance, a capacity of 10 milliontons opencast coal mine in 20 years has a potential to destroy around 800 ha of land
Drilling and blasting are the major unit operations in opencast mining. Inspite of the best efforts to introduce mechanization in the opencast mines, blasting continue to dominate the production. Explosives contribute currently about 5% of the direct cost of production and if the aggregate cost of drilling and blasting is taken together, this ...
Mining: "opencast mining" or "deep mining," 67% of USA mining is opencast. Pulverization: where coal is ground into a fine powder. Combustion: in the boiler (furnace), coal is burned to heat water create steam. Turbine: steam is superheated to 1,000 °F (540 °C) and moves through the steam turbine generator where it loses pressure ...

Surface Or Opencast Mining. Ppt On Opencast Coal Mining Vollendam. Mining Methods Coal is mined by two main methods surface or opencast mining and underground mining.. The choice of method is largely determined by the geology of the coal deposit; the majority of the world's coal reserves are recoverable by underground mining.
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
production by opencast mining. As the coal reserves suitable for extraction by opencast mining are becoming fewer in number, mining methods for safe and effective underground winning of coal are going to play an important role in future coal production. In India, coal seams of thickness or higher are called thick. Nearly 60% of the total

Typical dragline strip mining operation • Strip mining is accomplished by two techniques, area stripping and contour stripping. • Where coal beds are relatively flat and near the surface, area stripping is the dominant technique. In area strip mining, overlying material is removed from a seam of coal in long, narrow bands, or strips, followed by removal of the exposed coal.
