Intelligent mining has become the core technical support for the high-quality development of coal industry. After years of development, intelligent mining in China has formed four intelligent mining modes: intelligent unmanned operation of thin and medium-thick coal seams, man-machine-loop intelligent coupling high-efficiency fully-mechanized mining in large mining height coal seam, intelligent control and manual intervention to assist coal caving in fully-mechanized top-coal caving mining face, and intelligent + mechanized mining mode of complex conditions. In order to solve the problem of intelligent decision-making for fully-mechanized equipment in the working face, the intelligent collaborative control system (ICCS) of the working face has been developed to realize the self-adaptive coal cutting and self-sensing anti-collision of shearer, hydraulic power support, scraper conveyor and other fully-mechanized mining equipment based on the intelligent perception of coal flow, linkage control of fully-mechanized mining equipment, end and advanced support at working face. The above-mentioned research results have been applied in the Jurassic 1.1 m hard coal thin seam of Northeern Shaanxi, the fully-mechanized mining of the Jinjitan Coal Mine with an ultra-large cutting height of 8 m and the fully-mechanized top-coal caving mining in the Jinjitan Coal Mine of 9 m or more hard coal and extra-thick seams, the effects were remarkable. It has realized high-efficiency and intelligent unmanned mining in the Jurassic 1.1 m hard coal thin seam of northern Shaanxi, man-machine-loop intelligent coupling high-efficiency fully-mechanized mining with 8 m super large mining height, and intelligent fully-mechanized caving mining with ultra-large mining height for hard coal and extra-thick seam over 9 m.
