摘　　要：为提高对采煤工作面内部冲刷带等地质构造异常体探查准确性,利用无线电波透视方法进行现场应用试验,并通过模拟信号收发两端接收场强绘制出变化曲线,总结规律性分布特征,当电磁波穿透异常区域后,曲线分布呈现出“蝙蝠翼状”的明显特征,且异常构造体对信号具有较强的吸收衰减影响,经过试验论证与正向推演,证明采用无线电波坑透物探方法对冲刷带的范围探查与精度确定具有科学依据和可靠性。In order to improve the accuracy of exploration of geological structure anomalies such as the scour zone inside the coal face,field application tests are carried out by using radio wave perspective method,and the change curve is drawn by simulating the received field strength at both ends of signal sending and receiving,and the regular distribution characteristics are summarized.When electromagnetic wave penetrates the abnormal area,the curve distribution presents an obvious feature.Moreover,the abnormal structure has a strong effect on the absorption and attenuation of the signal.Through the experimental demonstration and forward deduction,it is proved that the radio wave pitting geophysical prospecting method has scientific basis and reliability for the scope exploration and accuracy determination of the scour zone.
