On Alternative Technology to Conventional Coal

On alternative technology to conventional coal mining and in fact this applies up to x for opencast and between x and JC for underground mining. On the other hand, in the case of a curve such as k , only opencast mining under favourable conditions is more economic, that is to say that up to abscissa point x it is less costly than extraction via boreholes. Line k shows the variants in which the ...

The conventional mining techniques described above, made up of the cyclic operations of cutting, drilling, blasting, and loading, developed in association with room-and-pillar mining. The oldest of the basic underground methods, room-and-pillar mining grew naturally out of the need to recover more coal as mining operations became deeper and more expensive. During the late 1940s, conventional ...

Coal mining - Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a pit, and the ...

Coal seams as much as five metres thick can be mined in a single “lift” by the longwall method, and seams up to seven metres thick have been extracted by conventional mining systems in one pass. However, when a seam exceeds these thicknesses, its extraction usually involves dividing the seam into a number of slices and mining each slice with longwall, continuous, or conventional mining ...

10 Different Types of Mining Operations and Mines

This form of mining involves mining the coal seam in a checkerboard style, which leaves pillars of coal that support the roof. This, in turn, makes it faster to get to the coal access with low invest, when compared to longwall mining. In room-and-pillar mining, however, only 50% to 75% of the coal

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
