摘要
综采放顶煤工艺现在被广泛应用,所采煤层厚度增加,工作面出煤量大幅增加,同时上覆岩层的结构也变得复杂化,运动特点更强烈。从支护方式和顶板变化入手,对不同支护下工作面矿压显现规律进行研究,供广大同行进行参考。
Roof fall technology at the fully mechanized caving face is now being widely used. With the seam thickness for extr- acting increasing, the coal output at the working face is increasing, while at the same time, the structure of overburden is becom- ing more complicated, and the movement characteristics is more obvious. This paper studied the law of rock pressure under varied supporting at the fully mechanized caving face from the supporting methods and the changes of the roof, providing references for the vast number of colleagues.
