摘要
为解决断层带巷道围岩控制难题,以马兰矿28311轨道巷揭露多条断层为工程背景,提出了断层带区域性支护思路和原则,包括断层带区域围岩注浆改性强化、高强度主动支护、支护材料匹配,设计了支护与参数,实现了巷道稳定控制。
In order to solve the problem of surrounding rock control of roadway in fault zone,based on the engineering background of exposing several faults in the 28311 track roadway of Malan Coal Mine,the ideas and principles of regional support in fault zone are put forward,including fault zone regional surrounding rock grouting strengthening,high strength active support,support material matching,support and parameters are designed,and roadway stability control is realized.
