In order to improve the mining efficiency of fully-mechanized mining face and accelerate the popularization and application of intelligent mining technology, the key factors affecting the mining efficiency, including cutting speed of shearer, following speed of hydraulic support, conveying capacity of scraper conveyor, collaborative planning of mining path and so on, were analyzed with the target of ten million ton production capacity of 2~3m medium thick coal seam. The development process and advanced cases of key technologies of rapid coal mining at home and abroad are briefly described, including the high efficiency mining technology of about 2m coal seam in Tunnel Ridge mine in America and the 3~4m high efficiency intelligent mining face with a capacity of ten million tons in Zhuanlongwan coal mine in China. The specific research direction and target of localization technology and equipment for fast coal mining with ten million ton capacity in medium thick coal seam are put forward: the length of mining face over 400m; shearer running speed up to 15m/min; 6s following speed of hydraulic support; scraper conveyor speed up to 2m/s and chain dynamic management technology, at the same time strengthen the reliability of equipment and system to ensure that the daily operation time increased to more than 20h.This paper provides a reference for the technology research and engineering construction of rapid coal mining in medium-thick coal seams.
