摘要
本文介绍了电磁波基本理论和层析成像技术的基本原理,建立了含断层和陷落柱构造的地球物理模型,模拟了工作面内断层和陷落柱构造的电磁波响应曲线,分析了曲线规律,并基于SIRT算法对物理模型成功地进行了反演。结合羊东矿实际探测资料,成功预测了工作面内的隐伏地质构造。物理模拟和实际探测效果都表明,无线电波透视技术探测井下隐伏地质构造是十分有效的。
This paper introduced the basic theory of electromagnetic wave and the basic principle of tomographic imaging,established a geophysical model with fault and collapse column structure,simulated the electromagnetic wave response curve of fault and collapse column structure in working face,analyzed the curve law,and successfully inverted the physical model based on SIRT algorithm.Combined with the actual detection data of Yangdong Mine,the concealed geological structure in the working face was successfully predicted.Both physical simulation and actual detection results showed that radio wave perspective technology was very effective in detecting underground concealed geological structures.
