摘要
Abstract
In Shanxi Changyuhe Coal Industry,when mining No.15 coal seam,the mining dynamic pressure and the strata movement in the goaf have great pressure on the east wing belt roadway and the east wing auxiliary transportation roadway,and there are roof subsidence,floor heave,two sides convergence,I-shaped steel shed deformation and other phenomena.In view of this problem,in order to ensure the safe and smooth mining of the 15108 working face in the eastern mining area of the mine,it was decided to carry out the roof cutting and pressure relief project.Through analysis and research,it was decided to carry out ultra-deep hole high-level roof cutting blasting in the East Wing Auxiliary Transportation Lane,and the key layers,blasting borehole layout and parameters were studied and designed.The practice shows that the designed roof cutting blasting scheme has a good implementation effect,the mining dynamic pressure of the working face is effectively blocked,and there is almost no pressure appearance during the mining period.关键词
