摘要
本文以48709厚煤层工作面为工程背景,分析了沿空留巷覆岩结构,并对膏体充填沿空留巷施工工艺进行了介绍,使用沿空留巷技术不仅有效缓解了该矿采掘接替紧张局面,同时实现了Y型通风,解决了工作面瓦斯问题,通过技术及经济效果分析,取得了良好的效果。
This paper takes 48709 thick coal seam face as engineering background, this paper analyzes the overlying rock structure along the Goaf, and introduces the construction technology of the paste filling along the goaf, which not only relieves the tension of the mine excavation,but also realizes the Y-type ventilation and solves the gas problem of the working face. Through the analysis of technical and economic effects,good results have been achieved.
