井下巷道掘进过断层探究

Discussion on Underground Roadway Excavation Crossing Faults

巷道掘进作业作为井下生产持续、有效开展的必要前提,确保巷道掘进期间的安全意义重大。以此为着手点,针对井下巷道掘进过断层开展探究,结合具体工程实际,在分析原支护方式存在问题的基础上,提出“钢棚+注浆”的支护优化方式,并对该方式的具体应用做出全面分析,希望能够为其他矿井巷道掘进过断层作业提供借鉴和参考。

As a necessary prerequisite for continuous and effective development of underground production,roadway excavation operations are of great significance to ensure the safety during roadway excavation.Taking this as a starting point,the discussion was carried out for the underground roadway excavation crossing faults.Combined with the actual project,based on the analysis of the problems in the original support form,this paper proposed the support optimization method of"steel shed+grouting",and made a comprehensive analysis on the specific application of the method,hoping to provide reference for the operation of roadway excavation crossing faults in other mines.
