| 摘 要： | 平煤八矿戊9.10-12160孤岛面开采煤与瓦斯突出、冲击地压及二者耦合作用下的复杂矿井动力灾害成为掘进和回采过程中的重大安全隐患。为了减轻上部已赋存有外错尾巷的戊9.10-12160工作面机巷冲击与突出危险,利用FLAC数值模拟软件模拟应力分布状况并选择能使机巷处于外错尾巷卸压区域内的方案,经理论分析和现场实践检验该方案外错尾巷起到了能量释放的作用,预防突出和冲击地压效果较好,减少了执行防冲减突措施时间和费用。

| Abstract: | On the fifth 9.10-12160 island face of Pingdinshan No.8 mine,gas burst,rockburst,and other dynamic hazards under the coupling effect of gas burst and rockburst are seriously dangerous in the mining process.To lessen the impact on mechanized roadway and the burst danger existing among the working face,FLAC software is used to simulate the stress distribution and the scheme of the mechanized roadway locating in the stress-relax area of outward tailing roadway is selected.By the theoretical analysis and practi... |
