高水材料充填技术在过超高空巷的应用

Application of High Water Material Filling Technology in Overpass High Altitude Roadway

为解决榆树坡公司2#煤层1201工作面过超高空巷的问题,对过超高空巷高水材料充填技术进行研究,选择充填工艺与系统,对实际应用效果进行分析评价。结果显示,工作面回采过空巷期间未出现矿压显现剧烈现象。

In order to solve the problem of super high-altitude roadway in working face 1201 of No.2 coal seam of Yushupo Company,the high water material filling technology of super high-altitude roadway was studied,the filling technology and system were selected,and the practical application effect was analyzed and evaluated.The results show that there is no serious phenomenon of mine pressure during stoping in the roadway.
