煤层冲刷带构造的存在会给煤炭企业的经济效益及安全生产带来不利影响。潞宁煤业公司22123工作面位于侏罗系大同组上部的2号煤，根据工作面的采掘及探测情况，发现其工作面中存在大量不规则冲刷带。为对其实施精准探测，采用数学建模软件MATLAB建立了煤层冲刷带地质模型，结合探地雷达数值模拟软件gprMax开展了正演模拟研究，得出不同雷达频率及钻孔间距的探测结果，分析总结得出钻孔雷达在工作面探测的最优频率及钻孔雷达探测时的最优探测间距。

The existence of coal seam scouring zone structure would bring adverse effects to the economic benefits and safety production of coal enterprises. The No.22123 Face of Luning Coal Industry Company was located in No.2 coal in the upper part of Jurassic Datong Formation. According to the mining and detection of the working face, it was found that there were a large number of irregular scouring zones in the working face. In order to carry out accurate detection, the mathematical modeling software MATLAB was used to establish the geological model of the coal seam scouring zone. Combined with the ground penetrating radar numerical simulation software gprMax, the forward modeling research was carried out, and the detection results of different radar frequencies and borehole spacing were obtained. The optimal frequency of borehole radar detection in working face and the optimal detection spacing of borehole radar detection were analyzed and summarized.
