摘要
通过分析柳新煤矿深部软岩煤巷的破坏机理、变形规律,提出了软岩巷道控制的原则,经过计算和数值模拟,确定了该矿2119工作面回采巷道合理支护参数,取得了较好的应用效果。
The law of deformation and mechainsm of destruction of Liuxin mine are analyzed in de- tail, the principle of soft rock control of Liuxin mine is put forward. The reasonable supporting parameters of 2119 working face is determined by adoptting the caculation and numerical simulation method. The re- search results in this paper achieved goog application effect.
