摘　　要：本文以金川矿区西二采区1454分段进路方向布局为研究对象,根据现场实际提出进路方向变更的可行性方案,对不同方案的优缺点进行对比,选择可操作性强、劳动强度低、施工效率高、安全性好的最优方案实施。以减小矿体端部与断层的接触面积,从而降低大面积垮帮的风险,提高不良岩体回采的安全性。同时,在此过程中总结的一些思路、方法可以为类似的采矿过程提供借鉴。Taking the layout of the 1454 section of the west second mining area of Jinchuan as the research object,this article proposes a feasible plan for changing access road,compares defects and merits of various plans,and selects and implements the optimal plan with high operability,low labor intensity,high construction efficiency and fine stability,so as to reduce contact area of ore body top with fault,cut down the risk of rock wall spalling,and improve the safety of stopping in poor rock mass.At the same time,some ideas and methods summarized in this process can provide references to similar mining processes.
