Abstract: Aiming at the problems of insufficient spatial adaptability, low equipment intelligentization level and others in the traditional process, taking the mining of extremely thin coal seams under complex geological conditions as the research object, a construction path for intelligent mining technology system is proposed. Through developing an electro-hydraulic control hydraulic support with a minimum support height of only 0.45 m, designing a specialized shovel plate mechanism suitable for thin coal seams, and constructing a closed-loop control system of "perception-decision making-execution" that integrates multi-source information fusion algorithms, dynamic adaptation and efficient collaboration of coal mining equipment are achieved. The application results show that the single shift raw coal yield is increased from 182 t to 364 t, achieving a yield doubling; Meanwhile, the comprehensive cost per ton of coal is decreased by 16.5%, and the utilization rate of working face resources is improved from 68% to 89%, which effectively reducing energy consumption and safety risks. The research results verify the feasibility of intelligent mining of extremely thin coal seams, and provides solid technical support for the safe and efficient development of scarce coal resources under complex geological conditions.
