火铺煤矿综采工作面矿压规律研究
Research on ore pressure law of the fully-mechanized mining face in Huopu Coal Mine
摘要
Abstract
In view of the situation that the coal seam is soft and broken,and the coal wall is easy to collapse and roof collapse,taking No.21170 fully-mechanized mining face as the engineering background,the deformation and breaking laws of the basic roof of the work-ing face are studied by using theoretical analysis,field monitoring and other methods,and the ore pressure manifestation laws are ob-tained.The research results show that the average weighting interval of the basic roof cycle is 13.7 m,the average end of cycle resist-ance of the middle support is greater than that of the upper and lower support,and the management of the working face transportation and return airway should be strengthened.The research can provide useful reference for the subsequent efficient mining of the No.17 coal seam in the mine.关键词
