摘要
针对大兴煤矿强冲击首采面的防冲安全要求,通过分析采空区瓦斯运移规律,制定相适应的瓦斯治理方略。总结“三巷、两孔、一埋”瓦斯治理方略的抽采效果,分析强冲击首采面瓦斯治理方略的合理性、有效性、差异性。
According to the anti-erosion safety requirements of strong impact first mining face in Daxing Coal Mine,the corresponding gas control strategy is formulated by analyzing the law of gas migration in goaf.The extraction effect of the gas control strategy of"three lanes,two holes and one filling"is summarized,and the rationality,effectiveness and difference of the gas control strategy in the first mining face with strong impact are analyzed.
