Development of China's Coal Mining Technology and Equipment

摘要

Strategic position of coal in China and three development stages of long wall mining technology and equipment, together with the last ten years important development achievements of mining 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 the completed technology and equipment for 6 million tons in one long wall face, the key technique and equipment of long wall face for 35° ~55° inclined seam, the completed technology and equipment for 10 million tons in high cutting long wall face, the top coal caving long wall mining technology and equipment for 20 meters coal seam. At last, it presents the development directions and prospects of China's coal mining technology and equipment.
