【摘要】 基于发生冲击地压、煤与瓦斯突出耦合型灾害情况,以山西某矿11061工作面为例,通过现场调查和数值试验,对底板瓦斯排放孔、底板排粉泄压孔、巷帮卸压抽采孔和煤层注水等关键要害部位提出了具有针对性的灾害防治措施,对该工作面存在的冲击地压危险状态进行了观察分析,提出了预抽采瓦斯和煤层注水的解决方案,为有效治理耦合型煤与瓦斯动力灾害提供了可借鉴的经验。更多还原

【Abstract】 Based occurred burst,coal and gas outburst coupled disasters,took 11,061 working face in some mine of Shanxi for example,through field investigation and numerical experiments on the floor gas discharge hole,bottom row of pink relief holes helped relief pumping. Alley coal seam mining holes and other key vital parts made disaster prevention measures targeted,the dangerous state of rock burst in the working face was observed. Coal seam gas extraction solutions for the effective governance coupled coal was put forward,which provided valuable experience for controling coupled mine and gas power disaster.更多还原
