基于瑞利面波法的岩溶地区注浆治理研究

通过面波法对煤矿地面的勘探，分析岩石裂隙充填前后波速大小特征及变化差异，判定灌浆整治结果。以压水试验法及钻芯取样检测法验证，分析灌浆法对于矿山塌陷的治理程度。面波法成功应用于贺州市平桂大岭煤矿，对开采枯竭地表塌陷煤矿在注浆前与注浆后分别采取面波法进行测试，其主要通过对比其波速和频散曲线形态来判定岩溶通道注浆效果。结果表明：钻孔的面波波形在0-20道垂直v分量上较完整，而且频率较高、宽度较大，呈现出完整的倾斜直线，表明同一层介质中波速反馈表现为一致性，没有出现缺失，即在注浆处理后，空洞、大裂缝被较好填充，形成了一个完整的介质体。

USE OF RAYLEIGH SURFACE WAVE METHOD IN GROUTING TREATMENT IN KARSTIC COLLAPSE

Through the surface wave method to the exploration of the coal Rayleigh Surface, the characteristics and variation of wave velocity before and after rock fracture filling were analyzed and the grouting control results were determined. The pump-in test method and the core sampling method were used to verify the treatment of mine collapse. Surface wave metho dissuccess fully applied in Hezhou Guangxi Daling coal mine. The surface wave method was used to test the ground collapse coal mine before and after grouting, respectively adopt surface wave method to test, mainly through comparing the wave velocity and dispersion curve to determine the karst tunnel grouting effect. Results show that the drilling of the surface wave shape on the 0 to 20 v perpendicular is complete, and higher frequency, width is bigger, showing a full tilts traight line, show that in the same layer medium wave velocity feedback performance consistency, nodeficiency, after grouting hole, large cracks were better filling, forming a complete dielectric body
