摘　　要：对回采巷道挖掘过程中掘进巷道与采煤工作面发生交锋现象的支护设计进行了分析。首先要对挖掘的回采巷道和工作面进行深入的调查,然后进行相应的分析,采取锚网配合锚索的方式进行加固。在加固过程中,要实时观测巷道周围岩土的形变量,并采取相应的措施。双层结构具有较好的防护效果,但有一定的经济成本,因此要考虑开采环境,合理选择双层支护的范围。The roadway excavation process,confrontation phenomenon and the coal mining face,take measures to strengthen the supporting is analyzed.This paper investigate the mining roadway and working face,and then analyzes the corresponding,takes the anchor with anchor cable reinforcement method.In the process of reinforcement to rock around the roadway deformation observed in real time,and takes corresponding measures.The double-layer structure has a good protective effect,but it has certain economic costs.Therefore,it is necessary to consider the mining environment in a reasonable choice of double layer supporting the scope of research.
