Development of China’s Coal Mining Technology and Equipment

摘要

Strategic position of coal in China and three development stages of long wall miningtechnology and equipment，together with the last ten years important development achievements ofmining technology and equipment were discussed. It introduces the main technology innovations，technical characteristics and application effects of some important projects in the field，such as thecompleted technology and equipment for 6 million tons in one long wall face, the key techniqueand equipment of long wall face for 35° ～55° inclined seam, the completed technology andequipment for 10 million tons in high cutting long wall face, the top coal caving long wall miningtechnology and equipment for 20 meters coal seam. At last, it presents the development directionsand prospects of China’s coal mining technology and equipment.
