机械锚头中空注浆锚索在付老庄铁矿巷道支护中的应用

Application of Mechanical Anchor Head Hollow Grouting Anchor Cable in Roadway Support of Fulaozhuang Iron Mine

为解决付老庄铁矿井下高应力软岩且围岩破碎巷道支护困难,围岩变形或帮顶垮落等问题,采用中空注浆长锚索配合新型复合注浆材料对其进行支护;支护效果表明采用该种支护形式不仅安全系数高,效率高,而且降低了施工成本,提高经济效益,具有良好的推广应用前景。

In order to solve the problems of high-stress soft rock underground in the Fulaozhuang Iron Mine and the difficulty of supporting surrounding rock broken roadway,deformation of surrounding rock or collapse of roof,hollow grouting long anchor cable and new composite grouting material are used;The support effect shows that the use of this type of support not only has a high safety factor and high efficiency,but also reduces the construction cost,improves the economic benefits,and has a good prospect of promotion and application.
