Huojitu coal mine is restricted by press ventilation and complex geological conditions, so it is difficult to mine medium and thin coal seams. For this reason, the mine introduces advanced equipment at home and abroad, intelligent system of fully mechanized mining face and machine following intelligent technology. In the stage of industrial application, two-way automatic memory coal cutting of Aikov SL300/6590 double drum shearer and SAC electro-hydraulic control system are introduced, which have been verified. 22 Shang 302 fully mechanized mining face has achieved 18 continuous advances per day, the number of operators in the production shift of the working face has been reduced from 12 to 4, the production efficiency of raw coal has been greatly improved, and the safety concept of "safety without people" has been further realized. the economic expenditure of the mining side has been reduced, the production time affected by equipment failure has decreased by 23.8% compared with the same period last year, and the loss of raw coal has decreased by 8.9% compared with the same period last year. The yield of commercial coal has increased from 65% to 73%, improving work efficiency and coal quality, and providing a guarantee for the safe and efficient production of coal mines.
