· During the lucrative 2000s commodities boom many new coal mining companies were established in Indonesia while existing coal miners raised investment to expand production capacity. This caused a severe supply glut that was exacerbated by coal miners' eagerness in the years to produce and sell as much coal as possible amid low global coal prices in order to generate .
Mary McMahon Entrance to a coal mine. Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ...

· Coal is a nonrenewable fossil fuel that is combusted and used to generate electricity. Mining techniques and combustion are both dangerous to miners and hazardous to the environment; however, coal accounts for about half of the electricity generation in the United States.

· According to CBECI, Bitcoin mining alone consumes an estimated median average of TWh (Terawatts per Hour) of electricity every year. By comparison, United Arab Emirates consumes TWh across all uses of electricity, Argentina 121 TWh, and Norway (at 29 in the global league of consumers) TWh.
· Due to their extreme sensitivity to heat, friction, impact, static electricity. Mercury fulminate, lead azide or PETN (or penthrite, or more properly Penta Erythritol Tetra Nitrate) are good examples of primary explosives used in the mining industry. They can be found in blasting caps and detonators .

At the beginning of the war miners were the largest single group of industrial workers in Britain. Coal production increased during the first few months of the conflict. This was mainly due to a greater commitment of the labour force in maximizing output. However, by March 1915, 191,170 miners joined the armed forces.

· 1. Introduction. During mining of seams of mineral rawmaterial, air is polluted with dust. Dust is moving together with the ventilation air (Bhaskar, 1986) and it settles at the wall and equipment in the excavation (Nawrat et al., 2002, Prostański, 2015).Dust presented in the ventilation air poses a risk to health and it has negative influence on working conditions.
Coal mining releases toxic materials into the soil and water. Bad mining can start coal fires which can burn for decades – releasing "fly ash" and smoke filled with greenhouse gases and toxic chemicals. It releases coal mine methane which is 20 times more powerful than carbon dioxide.

A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
