摘要:

为避免工作面搬家、保证工作面的连续开采以及节省巷道掘进的高额费用,新庄孜煤矿66310大倾角薄煤层保护层综采面采用调斜开采。根据具体的地质及生产技术条件,确定了调斜开采技术参数及运煤系统改造设计方案,现场采取了加强运输巷拐点附近大断面巷道的顶板管理、工作面输送机滑移的控制、工作面支架的调整等一系列管理措施。通过合理设计和现场精心组织,此次调斜开采取得了良好的技术经济效果。

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
