底抽巷二次锚网索喷协同支护技术研究与应用

Research and Application of Secondary Bolt-mesh-cable-shotcrete Combined Support Technology in Bed Plate Roadway

为减少回采面底抽巷受采动影响变形破环,确保工作面回采后底抽巷仍能满足使用需要,对回采工作面内底抽巷变形控制进行了探索研究,通过对变形巷道监测及破坏特征等因素的分析探究,采用二次锚网索喷协同支护技术,实现了巷道在受采动影响情况下变形量在可控范围之内,为接替工作面瓦斯治理工程按计划实施和矿井安全高效生产提供了保障。

In order to prevent the deformation and damage of bed plate roadway affected by mining, and ensure that the bed plate roadway still can be usable after stoping, the deformation control of the roadway in the mining face is investigated and studied. Based on the analysis and research of monitoring and failure characteristics of deformation roadway and other factors, the secondary bolt-mesh-cable-shotcrete support technology is adopted to realize the controllable deformation of the roadway under the influence of mining, which guarantees implementation of gas control project and the safe and efficient production of the coal mine.
