Summary on the bottleneck of intelligent fully mechanized caving mining technology and equipment in extra thick coal seam

The working face is easy to deform in the process of fully mechanized caving mining in extra thick coal seam, it is necessary to strengthen the research on the structure of mining strata, so as to improve the mining rate and reduce the incidence of safety accidents in mining. The above problems can be solved by adopting intelligent mining. This paper mainly summarizes the practice of intelligent fully mechanized caving mining technology and technical equipment in extra thick coal seam, analyzes the technical and equipment bottlenecks of intelligent caving, intelligent rapid tunneling of roadway and intelligent control of working face straightness, and looks forward to the possible development direction. Through solving the technical problems of mining imbalance and realizing the integration of new technologies, it is expected to break through the bottleneck of intelligent fully mechanized top coal caving mining technology and technical equipment in extra thick coal seam, and finally realize the goal of intelligent fully mechanized top coal caving mining in extra thick coal seam. It is hoped that this paper can provide some technical support and reference for the safe and efficient mining of extra thick coal seam in China
