| 摘 要： | 近年来,无煤柱开采是煤矿开采的发展趋势。为了实现无煤柱开采,可采用沿空留巷和沿空掘巷两种方式。考虑到沿空留巷的应用效果差,很多煤矿已经研发出了柔模混凝土巷旁支护技术来进行沿空掘巷,并已取得了不错的效果。分析了柔模混凝土巷旁支护技术的设计,并探讨了其施工工艺,可为实现无煤柱开采提供一定的参考。

| Abstract: | In recent years,pillar-free mining is the development trend of coal mining.In order to achieve pillar-free mining,gob side entry retaining and gob side entry driving can be used.Taking into account the poor application effect of gob side entry retaining,many coal mines have developed roadside support technology with flexible formwork concrete to carry out gob side entry driving,which have achieved good results.This paper analyzed the design of roadside support technology with flexible formwork concrete,and discussed its construction technology,which can provide certain reference for the realization of pillar-free mining. |
