切眼过高冒区综合加固技术研究与应用

Study on and Application of Integrated Strengthening Technique for Opening Off-cuts through High Risk Areas

针对王庄煤矿在掘进煤柱工作面、边角煤工作面顺槽巷道时遇到的困难,为改进施工工艺、提高掘进效率,论述了切眼过高冒区综合加固技术的施工工艺、支护措施、安全技术措施,为今后类似的巷道掘进提供技术保障,

In the light of some difficulties occurring in roadway tunneling of coal pillar mining face and cutout coal mining face in Wangzhuang Coal Mine,and in order to improve the construction technique and increase the tunneling efficiency,this paper studies the integrated strengthening technique for opening off-cuts through high risk areas was carried out including the construction process,supporting measures,and technical safety measures for providing technical guarantee for similar tunneling work in the future.
