摘　　要：以一煤矿12162作业面为例,介绍一种巷道中锚网索联合支护方案。通过相关计算确定出锚网索支护体系中锚杆与锚索的参数,并以此为基础设计出多种不同的支护方案,之后利用有限元分析的方式对各方案进行模拟分析,以此选取出最佳的锚网索联合支护方案。通过锚网索联合支护方案的应用,可显著提升巷道作业面的稳定性。确认该方案具有一定应用价值。Taking the 12162 working face of a certain coal mine as an example,a combined support scheme of bolt-net-cable in the roadway was introduced.Through relevant calculations,the parameters of bolts and cables in the bolt-net-cable support system were determined,and based on this,multiple different support schemes were designed.Then,finite element analysis was used to simulate and analyze each scheme,in order to select the best bolt-net-cable combined support scheme.The application of bolt-net-cable combined support scheme can significantly improve the stability of the roadway working face,confirming that the scheme has certain practical value.
