沿空留巷在瑞东煤矿的应用

Application on Goaf Side Entry Retaining in Ruidong Coal Mine

沿空留巷是实现无煤柱开采的主要技术措施之一。为最大限度提高资源回收率,有效降低巷道掘进率和掘进成本,瑞东煤矿在6#煤层采用了沿空留巷技术。本文以60101采煤工作面为例,介绍了沿空留巷在实践中的应用。分析了沿空留巷巷内支护、巷旁支护等方面存在的问题,采取了针对性措施,达到了预期效果,取得了可观的经济效益,为该矿开采6#煤层提供了借鉴和指导。

Goaf side entry retaining is one of the main technical measures which achieve without coal pillar min ing. To maximize resource recovery, reduce tunneling rate and excavation costs, Ruidong coal mine used the technol ogy of goaf side entry retaining in 6# coal seam. In this paper, takes 60101 working face as an example, introduces the practical applications of the technology. And analyzes some existing problems, such as goaf side entry retaining roadway support, roadside support and other aspects, and takes pertinence measures, achieves the expected results, obtains considerable economic benefits. It provides a reference for 6# coal seam mining.
