摘　　要：回采巷道的支护对于煤矿安全生产具有重要意义。结合山西某矿的实际情况,采用工程类比法确定了锚杆锚索支护的参数,并通过岩石力学公式对锚杆锚索参数进行了校验。同时对地质构造区的支护进行了设计,各项设计参数均满足设计要求。根据巷道顶板的实际情况对锚杆锚索的支护参数进行相应调整优化,实现了预期的支护效果。The support of back mining roadway is of great significance to the safe production of coal mines.Combining with the actual situation of a mine coal industry,the parameters of anchor rod and anchor cable support were determined by the engineering analogy method,and the anchor rod and anchor cable parameters were calibrated by the rock mechanics formula.At the same time,the support in the geological structure area was designed,and all the design parameters met the design requirements.The support parameters of anchor rod and anchor cable were adjusted and optimized accordingly according to the actual situation of the roadway roof,and the expected support effect was achieved.
