Abstract: Aiming at the existing problems in aspects of production efficiency,labor intensity,and security guarantee in the fully mechanized mining face of Zhaolou Coal Mine,taking the 7301 working face as the object,the intelligent coal mining technology has been constructed by applying key intelligent technologies such as remote power supply and liquid supply,new walking self moving train,monorail hanging cable landing device,etc.Long distance and remote power supply and liquid supply realize long-distance and high load operation,step by step self moving train improves equipment centralized management and transportation efficiency,monorail hanging cable landing device reduces labor intensity,shearer video servo system realizes video monitoring of the whole process of coal cutting,and "three machines" automatic speed regulation technology of working face improves equipment coordination efficiency;Personnel access and intelligent lubrication system reduce safety accident rate and equipment failure rate;The communication and liaison system strengthens the production scheduling and early warning capabilities.The application results show that the production efficiency of the mine is increased by more than 20%,the number of staff is reduced by 40%,and the occurrence rate of safety incidents is reduced by 65%.The overall improvement of production efficiency,energy conservation and consumption reduction,and safety assurance is achieved,which provides a practical basis for the intelligent transformation of coal mines.
