Coal mining - Choosing a mining method | Britannica

Coal mining - Coal mining - Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic ...

Underground mining method selection by decision making ...

Underground mining method selection is one of the most important decisions that mining engineers have to make. Choosing a suitable underground mining method to extract a mineral deposit is very important in terms of economics, safety and productivity of mining operations.

Mining method selection by multiple criteria decision ...

Mining method selection by multiple criteria decision making tools by M.R. Bitarafan and M. Ataei* Synopsis Mining method selection is the first and most important problem in mine design. In this selection some of the parameters such as geological and geotechnical properties, economic parameters and geographical factors are involved.

The mining method selected for exploitation is determined mainly by the characteristics of the coal deposit and the limits imposed by safety, technology, environmental concerns, and economics.

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 – a pit, and the ...

Equipment selection for high selective T excavation ...

The choice of which mining method to use at many large surface coal mines is often dicated by what machinery is available or what experience the mine management can offer. One of the most significant surface coal mines in Turkey is owned and operated by the Turkish National Coal Board, located to the west of the city of Kütahya.

Selection of an Appropriate Mechanized Mining Technical ...

Mechanized mining technical process (MMTP) related to the control method of the shearer is a vital process in thin coal seam mining operations. An appropriate MMTP is closely related to safety, productivity, labour intensity, and efficiency. Hence, the evaluation of alternative MMTP is an important part of the mining design. Several parameters should be considered in MMTP evaluation, so the ...

Surface Coal Mining Methods in Australia - InTech

Surface Coal Mining Methods in Australia 5 2. Open cut mining methods strip mining Large-scale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significan t developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex and

Surface Mining Methods and Equipment

expensive surface mining method. Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside.

Coal Mining Methods

Coal Mining Methods Underground Mining Longwall & Room and Pillar Mining Longwall mining and room-and-pillar mining are the two basic methods of mining coal underground, with room-and-pillar being the traditional method in the United States. Both methods are well suited to extracting the relatively flat coalbeds (or coal seams) typical of

Appendix F: Underground Coal Mining Methods and ...

Underground Coal Mining Methods and Engineering Dust Controls. An underground mine consists of the portals (entrance and exits to the mines), mains, submains, panels, and working faces. The panels are the working sections of the production operation. Depending on the mining method, a working section can have one or more working faces.

Green coal mining technique integrating mining-dressing ...

This study proposes an integrated, closed-cycle mining-dressing-gas draining-backfilling-mining (MDGBM) technique. The proposed approach involves the mining of protective coal seam, underground dressing of coal and gangue (UDCG), pressure relief and gas drainage before extraction, and backfilling and mining of the protected coal seam.

Coal mining | World Coal Association

Coal is mined by two methods: s urface or ‘opencast’ mining or underground or ‘deep’ mining. The choice of mining method largely depends on the geology of the coal deposit. Underground mining currently accounts for a bigger share of world coal production than opencast; although in several important coal producing countries surface ...
