2020-10-23  At the tipple, the coal is dumped into a hopper that feeds the primary crusher, then is conveyedthrough additional coal preparation equipment such as secondary crushers and screens to the storage area. If the mine has open storage piles, the crushed coal passes through a coal stacker onto the pile. The piles,usually worked by bulldozers, are subject to wind erosion. From the storage area, the coal is conveyed to atrain loading facility and is put into rail cars. At a captive mine, coal will go from the storage

Equipment Selection for Surface Mining: A Review

2013-7-19  A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

Coal Mining: How Is Coal Mined? - Science ABC

2021-1-7  Surface mining and underground mining are the two major schools of coal mining. To qualify for surface mining, the coal deposits must be within 50-80 meters of the surface. The job of a miner primarily involves removing ‘overburden’— rock, soil, trees etc. – that mix with the coal deposits and cover them near the earth’s surface.
