Analysis on key technologies of intelligent coal mine and intelligent mining

In order to solve the outstanding problems faced by the coal mining,the key core technologies of the future development direction and the urgent breakthrough of the coal mining are found,the domestic and foreign energy struc- ture and the coal status are analyzed. It is pointed out that using the scientific and technological progress to realize the safe and efficient green mining and clean and efficient utilization is the development direction of the coal,and the de- velopment of intelligent coal mine is an inevitable choice for the development of the coal industry. The connotation of intelligent coal mine and three basic theoretical problems and research directions are put forward:① the unified ex- pression of multi-source and heterogeneous data and the information dynamic correlation relationship in digital coal mine;② the mechanism of complex surrounding rock environment-mining system and the theoretical basis of intelli- gent control of the whole path and attitude of equipment group;③ the system health condition prediction and mainte- nance decision-making mechanism of mine equipment group. Eight operational management platforms of intelligent MOS multi-system integrated management,underground robot cooperative intelligence and feed management,under- ground precise positioning and navigation and 5G communication management,geological and mine mining and trans- portation information dynamic management,video enhancement and real-time data-driven 3D scene reproduction re- mote intervention,environment and hazard perception and security early warning system management,systematic man- agement of intelligent unmanned working face and the health management of the whole mine equipment and facilities are conceived. The functions,characteristics and key problems of each platform are analyzed,and the corresponding construction paths and methods are put forward. By analyzing the composition and construction target of intelligent coal mine,the paper puts forward eight key technology short-boards and key technologies that need to be broken in intelli- gent mining,and puts forward the measures to promote the development in the aspects of both technology and manage- ment. At the technical level,there are three main directions:data acquisition and utilization,intelligent decision making and equipment R & D. At the management level,scientific production capacity layout,specialized operation service and the establishment of new standard rules and regulations system are put forward. The development goal and realiza- tion path of intelligent coal mine and intelligent mining technology are pointed out.
