浅部复杂地层巷道锚索网支护技术研究

Research on Anchor Spray Network Support Technology for Shallow Complex Strata Roadways

为了在浅部软弱易破碎地层中掘进时维持巷道围岩的完整稳定性,防止形成应力集中,通过利用锚索网支护技术对某矿+1 200 m掘进巷道顶板进行支护应用。结果表明,在浅部复杂地层中掘进时,锚索网支护技术能极大地提高巷道安全稳定性。

In order to maintain the complete stability of the surrounding rock of the roadway and prevent the formation of stress concentration when driving in the shallow soft and fragile strata, the application of anchor cable mesh support technology to the roof of the+1200M roadway in a mine has been carried out. The results show that the anchor cable mesh support technology can greatly improve the safety and stability of the roadway when driving in the shallow complex strata.
