摘要
锚杆支护是煤矿巷道最主要的支护方式,巷道支护关系着矿井的生产和矿山人员的安全,通过现场对不稳定大断面巷道锚杆锚网索的参数技术和布置方式的研究,证明锚杆锚网索联合支护可有效地减少巷道破坏,增强大断面巷道的稳定性,为巷道安全提供了有效保证。
Bolt supporting is the main support of coal mine roadway, the roadway support is related with the mine production and mine personnel safety, by researched on the instability of large section roadway bolt anchor cable technology parameters and layout in field. The results show that bolt mesh anchor combined support can effectively reduce roadway damage, enhance the stability of large section roadway, and provide a certain guarantee for the roadway safety.
