摘　　要：为解决工作面巷道采掘接替紧张,上隅角瓦斯聚集等问题,提出高水材料巷道充填沿空留巷技术,利用公式计算出巷旁支护体宽度为2.0m,针对原巷道支护强度低、锚固长度短的问题,补打锚杆锚索对支护体系进行补强,通过沿空留巷形成Y型通风系统,解决了工作面上隅角瓦斯积聚和超限的问题。通过矿压观测,留巷顶底板变形量保持在1.0~1.5m之间,满足巷道在回采期间通风要求。In order to solve the problem of mining displacement in the working face of Xinyuan coal industry and the gas accumulation in the upper corner, the roadway filling technology of high water material roadway filling is proposed, and the width of the roadside supporting body is calculated to be 2.0 m. The problem of low strength of the roadway support and short anchorage length is to reinforce the support system by the anchor bolt and the Y-shaped ventilation system through the empty roadway, which solves the accumulation and overrun of the gas on the working face. problem. Through the results of mine pressure observation: the deformation of the top and bottom of the roadway is kept between1.0-1.5 m, which meets the ventilation requirements of the roadway during the mining.
