This invention relates to an equipment for shortwall mining useful for extraction of pillars (2) in underground coal mines, which comprises a series of self-advancing powered supports (1) being placed along the pillars under extraction, the pillars being located within a panel (3) which is being surrounded by barrier pillars (4). An armoured face conveyor (5) is fixed to said barrier pillars.
The Argus Cogeneration Plant is a coal-fired power station located adjacent to the mineral processing plant in Trona, California.The power station has nameplate capacity of 63 MW and produced 296 GWh of electricity in 2018. It is the last coal-fired power station still operating in California. Unit 1 was commissioned in 1978 and has a nameplate capacity of 63 MW.

Longwall Mining of Coal. Longwall mining of coal is a high production and high productivity method, employing sophisticated electrical, mechanical, and hydraulic systems, as well as computer-based monitoring and control systems. Most modern (coal) longwall faces are semi-automated. It is noteworthy that longwall operations in trona mines utilize essentially the same equipment and …
Longwall mining is a form of underground trona or coal mining where a long wall of trona or coal is mined in a single slice, generally 0.5 to 1.0 meters thick. A number of hydraulic jacks called power roof supports, chocks or shields are placed side by side along the mining seam. The face is cut by a shearer which can weight between 75 – 120 ...
zero emissions power plant. Integrated coal gasification combined cycle (IGCC) plants are an example of the hydrogen route. Coal is gasified to form synthesis gas ( syngas) of CO and H 2. The gas then undergoes the water-gas shift, where the CO is reacted with steam to form CO 2 and H 2. The CO 2
