摘　　要：探讨了利用探地雷达技术进行强干扰区煤矿采空区精细探测的技术方法,结合雷达探测原理分析了灾害性采空区的探测可行性,给出了采空区的雷达反射波响应特征,分析了干扰的类型,提出了压制强电磁干扰的工作方法、数据处理和解释方法。结合具体的工程实例分析,论证了压制强电磁干扰方法的可行性,探测结果得到钻探验证,取得了较好的地质效果。研究表明,在强电磁干扰地区,采用可行的技术方法压制干扰,可以实现探地雷达进行灾害性采空区的精细探测。Discussed the detailed detection method of abandoned workings on strong interference area using ground penetrating radar（GPR） technology. On the principle of GPR, analyzed the feasibility of hazard abandoned workings detection ,displayed corresponding characteristics of radar reflection wave in abandoned workings, and analyzed the types of interference and proposed the working method, data processing and interpretation for suppressing strong elec- tromagnetic interference. Combined with the analysis of concrete detecting example, proved the feasibility of suppress- ing method for strong electromagnetic interference, and the detecting result was verified by drilling with desirable geo- logical effect. The research shows that, in the area of strong electromagnetic interference, the detailed detection of haz- ard abandoned workings by GPR can be realized by using feasible technical method to suppressing interference.
