Coal Exploration and Mining Geology

2020-8-18 · Coal mining geology activities include delineating in more detail any geological features that may affect the mine layout, such as individual faults and igneous intrusions, as well as monitoring any variations in the seam that may impact on the quality of the coal produced. They are also concerned

2020-7-11 · The modern mining process itself is a highly mechanised operation, and the selection of the mine layout to optimise equipment use is based on the mine design, to which geology is a major input. In modern‐day mining there are two basic methods of mining coal: underground mining and opencast or surface mining.

2020-12-1 · Mining geology: coal rider roof. Coal “riders” are rooted coal beds which occur above (usually within 7 m) principal correlated seams, and generally extend across much smaller areas than the underlying main seam. In some basins, coal riders are common (e.g., Horne et al., 1978a), but in the Desmoinesian of the Illinois Basin they are uncommon.

2021-12-8 · Mining. Coal is mined by both surface or ‘opencut’ (or opencast) and underground or ‘deep’ mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia’s coal is produced from opencut mines.

Coal Mining History . The discovery of coal in Colonial Virginia was first reported by Colonel William Byrd in 1701, who noted coal occurrences on the banks of the James River near the town of Manakin (Brown and others, 1952). Coal was likely being used for domestic purposes even earlier than that by Huguenot settlers (Wilkes, 1988).

Opencast mining is very efficient and production rates are high. Coal can economically extracted up to 100m in some cases 200m. Opencast mining is cheaper than underground mining, as expensive machinery not required and a smaller workforce needed. Ventilation equipment not needed. Smaller seams can be mined at a profit.
