Research and application of key technology for intelligent high-cutting fully mechanized working face in thick coal seam
In view of the problems of backward equipment and high mining cost in Fucun Coal Mine,and considering various factors such as safety,economy and resource recovery,it was proposed to build an intelligent high-cutting fully mechanized working face for thick coal seam in Fucun Coal Mine.According to the 3upper coal seam occurrence condition,the integrated equipment control platform was deployed in the intelligent working face,and the intelligent electrical control system of large mining height hydraulic support,the intelligent control system of coal shearer,and the mobile internet cloud storage system were also applied.And the key breakthroughs were made in the monitoring of the main equipment posture of the working face,the intelligent mining process of large mining height working face,remote control and centralized monitoring technology,which realized the autonomous positioning,memory cutting,automatic following and moving of the hydraulic support of the coal shearer,sequential start and stop with one-key,automatic sequential stop when fault occurs,and three-machine collaborative control;the mine information system was optimized and upgraded,and an intelligent fully mechanized working face internet cloud platform was established.Results show that,since the implementation at November 2017 in the 1008 working face,the production shift personnel was reduced from 12 people to 5,the daily production was 6000 t,the 6 m thick coal seam intelligent mining pattern was established.
