New development of intelligent mining in coal mines

Intelligent mining has become the core technical support for the high-quality development of coal industry.After years of devel?opment,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 min?ing mode of complex conditions.In order to solve the problem of intelligent decision-making for fully-mechanized equipment in the work?ing face,the intelligent collaborative control system(ICCS)of the working face has been developed to realize the self-adaptive coal cut?ting 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 work?ing 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-effi?ciency and intelligent unmanned mining in the Jurassic 1.1 m hard coal thin seam of northern Shaanxi,man-machine-loop intelligent cou?pling high-efficiency fully-mechanized mining with 8 m super large mining height,and intelligent fully-mechanized top-coal caving min?ing with ultra-large mining height for hard coal and extra-thick seam over 9 m.
