为探讨复杂条件下巷道支护困难的难题,结合某矿运输上山复杂的地质条件,在现有支护方案的基础上,通过对巷道支护效果的现场监测,得出巷道变形的特征,在此基础上,分析了巷道围岩破坏失稳原因,并针对性地提出了巷道围岩治理模式,为矿井后续巷道的支护决策提供参考依据。 In order to explore the difficult problem of roadway support under complex conditions, combined with the complicated geological conditions of a mine transporting up the mountain, based on the existing support schemes, the deformation characteristics of the roadway are obtained through on-site monitoring of roadway support effect. Based on the analysis, the causes of the failure of the surrounding rock of the roadway are analyzed, and the control mode of the surrounding rock of the roadway is put forward in order to provide reference for the support decision-making of the subsequent roadway in the mine.
