摘要
为了掌握沿空动压巷道围岩运动规律、矿压分布特征以及巷道围岩破坏范围,更好地控制巷道围岩,以东大煤矿12302及12306工作面为工程案例,研究了巷道围岩运动和矿压显现规律,并在此基础上提出煤柱优化及巷道支护优化方案。
In order to master the law of surrounding rock movement along the dynamic pressure roadway, the distribution of underground pressure and the scope of the surrounding rock damage, better control of the roof. Dongda coal mine 12302 and 12306 face as engineering case study of roadway rock movement and and the optimization scheme of coal pillar optimization and roadway support is put forward on this basis.
