On Alternative Technology to Conventional Coal

1979-1-1 · 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.

Coal mining Underground mining Britannica

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
