锚注技术在福建煤矿深部巷道复杂破碎围岩的应用

Study on AnchorInjection Technology Applied in Fujian Complex Crushed Surrounding Rock of Deep

结合龙岩市北山煤矿的地质条件,对煤矿深部复杂破碎围岩采用注浆锚固技术,优化了支护参数方案,并对巷道的顶板位移及离层量进行了现场监测,结果表明,锚注支护技术可以有效地对巷道复杂破碎围岩进行固化,有效地控制了巷道的变形,为实现矿井安全生产奠定了基础。

Based on engineering practice of Beishan Mine in Longyan city, anchor injection technology is put forward as a practical solution for complex crushed surrounding rock in deep coal mine, and displacement of Beishan mine roadway roof and roof abscission layer quantity were monitored for observing the supporting effect and the quality of grouting reinforcement. The support results show that anchor injection technology can effectively solidify complex crushed surrounding rock and control the deformation of roadway, which reflects good supporting effect.
