| 摘 要： | 煤矿采空区常常破坏其上覆岩土层的稳定性,使其产生变形,直至崩塌、塌陷、地裂等,对上方建筑物造成危害。为加固岩土层的稳定,常采用钻孔灌浆法,封堵采空区及岩土层裂隙。笔者介绍了超声波检测钻孔灌浆质量的方法原理并做了测试效果分析。

| Abstract: | The stability of the strata of a coal mine is seriously affected by the underlying worked-out area, which frequently causes deformation or even collapse, depression and geofracturing and hence gravely threatens the buildings above it. For the purpose of consolidating the rock and soil bed, drill-hole grouting has often be used to plug the worked-out area and fractures of the rock and soil bed. In this paper, the principle of applying ultrasonic wave method to detecting drill-hole grouting quality is described and the test result is analyzed. |
