Abstract:

In order to avoid face moves、 ensure the continuous mining of the working face and save the high cost of tunneling, adjustment inclination mining method is used by the 66310 inclined thin coal seam and protective layer fully- mechanized face of Xinzhuangzi Coalmine . According to the specific geological and technical conditions of production, the technical parameters of adjustment inclination mining and the design plan of transportation system change is determined, a series of management measures is taken in site,such as strengthening the roof management of large section roadway nearby inflection point in the transportation roadway、the slippage control of conveyor in the working face、adjustment the face support and so on.Through the rational design and well-organized in site ,good technical and economic results is achieved about this adjustment inclination mining .

Key words: inclined thin coal seam, key protective layer, fully- mechanized face, inclination adjustment with rotation mining
