动压影响下巷道掘进支护研究

Under the influence of the dynamic pressure roadway supporting research

横河煤矿根据接续要求,形成了顶分层后退开采,底分层巷道前进掘进的巷面相向采掘局面。1134东工作面的上、下顺槽均受1131东回采工作面的动压影响,且巷道顶板为厚度4.4m的顶煤,为了保证放顶煤工作面顺槽掘进安全,在巷道布置、巷道支护等方面入手,采取切实有效的技术措施,巷道矿压控制非常成功,取得了突出效果。

According to the requirements of coal mine in Henghe,formed the situation of the top slice retreating mining and the bottom layer heading face driving counter. The entries of 1134 east face are subject to the dynamic pressure effect from 1131 East working face,and the top coal thickness of roadway roof is 4. 4m,in order to ensure the top coal caving working face excavation,starting in roadway layout,roadway support and so on,take the practical effective technical measure,mining pressure control is very successful,has achieved remarkable results.
