the process and machinery of an opencast mine of coal

Jan 01, 1991 Jan 01, 1991 Abstract. This paper is concerned with the environmental assessment (EA) of opencast coal mining proposals. The paper includes: a description of the processes and activities involved in opencast coal mining operations, the mining methods used, and the types of plant and machinery used during the course of such activities; a description of the baseline environmental features which may be affected by opencast coal mining activities; an indication of the potential impacts which opencast coal

    Coal is mined either by surface methods (open-cut or open-cast 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 )

    THE OPENCAST MINING OF IRONSTONE AND COAL W. DAVID EVANS OPENCAST mining, or large-scale quarrying, of bedded minerals has been carried out in this country for over one hundred years. As distinct from underground mining it involves the removal of superincumbent strata, or overburden, which are discharged, or dumped, clear of the mineral exposed

    Mining and opencast mining in particular affect all components of ecosystems (Bradshaw, 1997).During opencast mining, material overlying the mined minerals, called overburden, is excavated and deposited in a heap. This heap can be located either inside the mine pit (an internal heap) or outside (an external heap)

    Dec 22, 2012 Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth’s surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal
