| 摘 要： | 通过数值模拟方法研究分析表明,由于9#煤的开采,10# 11#合并层开采顶板矿压显现明显减弱,从而使10# 11#合并层煤壁和顶煤顶板管理条件得到较大的改善,工作面支架能够得到较好的维护。研究结果为水峪煤矿10#-11#合并层开采方法选择提供了必要的理论依据。

| Abstract: | By numerical simulation, authors studied underground pressure of 10~#-11~# union seams' roofs. Because of mining in 9~# coal seam, underground pressure of 10~#-11~# union seams′roofs weaken distinctly,management condition of 10~#-11~# union seams′roofs improve;brackets can be maintenance better in working face.Result of research given theoretic gist for selection of mining method in 10~#-11~# union seams in Shuiyu mine. |
