杜儿坪矿切顶卸压自动成巷技术研究与应用

Research and Application of Automatic Road Forming Technology for Cutting Roof for Pressure Relief in Du'erping Coal Mine

为解决西山煤电集团公司各矿井生产衔接紧张的问题,通过设计,杜儿坪矿在62711工作面采用切顶卸压自动成巷无煤柱开采技术并进行了现场应用。应用效果表明:该矿留巷效果较好,在缓解各矿井衔接紧张和提高资源回收率方面具有很高的社会经济效益,该研究可为西山矿区各矿井提供借鉴。

In order to solve the problem of busy schedule of production link in coalmines of XiShan coal and electricity Group,the roof-cutting for pressure relief technology was introduced and applied to form roadway automatically without coal pillar in 62711 working face.The application results show that the practice is of good effect in social and economic benefits,also in alleviating the busy schedule of production link,and provide reference for other mines in Xishan district.
