林南仓矿断层破碎带巷道注浆-锚喷支护技术及应用

Technology of grouting-shotcrete support in fault fracture zones in Linnancang coal mine and the application

在全面分析研究林南仓矿-650回风巷道断层破碎带变形机理及破坏原因的基础上,采取"注浆-锚喷"支护措施,应用数值模拟进行论证,钻孔窥视观察巷道围岩内部结构,并对支护效果进行巷道位移监测。实践表明:该种支护方式改善了巷道围岩受力结构,有效控制了巷道变形破坏,确保矿井安全生产。

On the basis of comprehensive analysis and research deformation mechanism and failure reasons of Fault fracture zone of -650 air return roadway in Linnancang Coal Mine .Take the measure of“Grouting-Shotcrete Support” ,it demonstrated used to numerical simulation .Internal structure of roadway surrounding rock of drilling observed ,and the supporting effect of roadway displacement be monitor .The results show that it can improve the force structure and effectively control the deformation and failure of roadway ,then ensure the mine safety production .
