摘要
为合理开采矿山资源,提高巷道开拓效率,对巷道围岩裂隙进行探测分析,发现巷道围岩变形破坏比较严重,塑性区已变成松散区,巷道支护较为困难,通过对矿井开采方法、巷道准备与布置、施工技术以及支护措施进行详细介绍,并将该技术应用于深部矿井巷道施工中,取得了显著的应用成效。
In order to reasonably mine resources and improve roadway development efficiency,the cracks of roadway surrounding rock are detected and analyzed.It is found that the deformation and damage of roadway surrounding rock is relatively serious,the plastic area has become a loose area,and roadway support is difficult.Through the detailed introduction of mining methods,roadway preparation and layout,construction technology,etc,the technology has been applied to the construction of deep mine roadway,which has achieved remarkable application results.
