化学加固岩层的方法为矿山建设开辟了新方向。这种新方法在松软岩层的竖井掘进中,起到了积极防水效果。此外,它在井筒掘进直径轮廓线外围形成永久性的保护层,可作为竖井掘进和使用时的承载结构,这样就有助于采用高效掘进设备,还可降低对永久支护强度的要求。由于对树脂所加固的砂层的特性及状态缺乏足够的认识,因而没有 The method of chemical strengthening of rock strata opens up a new direction for mine construction. This new method has been shown to have a positive waterproof effect in shaft boring in soft rock formations. In addition, it forms a permanent protective layer on the periphery of the borehole diameter profile, which can be used as a bearing structure for shaft excavation and service, thus contributing to efficient excavation equipment and reducing the need for permanent support strength. There is no sufficient knowledge of the properties and state of the sand that is reinforced by the resin
