基于矿井音频电透视施工过程中巷道空间狭小、环境复杂、存在积水、金属等低阻体干扰的原因，电极的接地条件与环境等存在较大差异，导致探测数据一致性较差，干扰常导致真实的异常信号信噪比较低，给数据处理解释带来困难。为了解决上述问题，提出了矿井音频电透视数据的巷道围岩低阻体干扰校正方法。该校正方法是在充分分析了巷道中存在的低阻干扰体对探测结果影响的前提下，研究了矿井音频电穿透原理及方法，对巷道存在的低阻体干扰进行了数值模拟，使用小波变换的数据降噪方法进行处理，通过实测数据的分析验证校正方法的有效性。具体校正方法是根据不同发射点将矿井音频电透视数据进行分组并且绘制接收曲线；当不同发射点对应的接收曲线在同一接收点附近均出现畸变异常时，根据发射点不同进行分组的数据，在组内按照接收点坐标位置进行排序，应用小波变换对数据进行平滑处理；当同一发射点对应的接收曲线出现畸变异常时，按照接收点坐标位置排序并且进行圆滑处理，完成矿井音频电透视数据的校正。研究结果表明，在数据校正前，接收电位差数据会产生了较大偏差，通过巷道围岩低阻体数据校正方法使发射端或接收端低阻体干扰导致的视电导率畸变得到了很好的处理，既对低阻干扰体影响做了校正，又保留了可能存在的其他异常。通过对实测成果的数据校正，验证了该校正方法的预期效果，可以较好地解决矿井音频电透视存在的问题。数值模拟部分所做模型为二维模型，针对上述问题，若能建立三维模型，对低阻干扰体进行三维空间定位，将会取得更加精确的校正效果，达到矿井音频电透视精细化探测的目的。

Based on the reasons of narrow roadway space, complex environment, ponding, metal and other roadway surrounding rock low resistance body interference in the process of mine audio frequency electrical perspective construction, the electrode grounding conditions and the environment are quite different, resulting in poor consistency of detection data. Interference often leads to low signal-to-noise ratio of real abnormal signal, which brings difficulties to data processing and interpretation. In order to solve the above problems, this paper puts forward the interference correction method of low resistance body in surrounding rock of mine audio frequency electrical perspective data. On the premise of fully analyzing the influence of the low resistance interference body in the roadway on the detection results, the principle and method of mine audio frequency electric penetration are studied. The low resistance body interference existing in the roadway is numerically simulated, and the data denoising method of wavelet transform is used for processing. The effectiveness of the correction method is verified by the analysis of the measured data. The specific correction method is to group the mine audio electrical perspective data according to different transmitting points and draw the receiving curve; when the receiving curves corresponding to different transmitting points have abnormal distortion near the same receiving point, the data grouped according to the different transmitting points are sorted according to the coordinate position of the receiving point in the group, and the wavelet transform is used to smooth the data When the receiving curve corresponding to the same transmitting point has abnormal distortion, it is sorted according to the coordinate position of the receiving point and processed smoothly to complete the correction of the mine audio electrical perspective data. The results show that before the data correction, the received potential difference data will have a large deviation. The distortion of apparent conductivity caused by the interference of low resistance body at the transmitting end or receiving end can be well dealt with by the data correction method of low resistance body in surrounding rock of roadway, which not only corrects the influence of low resistance interference body, but also retains other possible anomalies. Through the data correction of the measured results, the expected effect of the correction method is verified, which can better solve the problems existing in the audio electrical perspective of the mine. The numerical simulation part of the model is a two-dimensional model. In view of the above problems, if we can establish a three-dimensional model to locate the low resistance interference body in three-dimensional space, it will achieve more accurate correction effect, and achieve the purpose of fine detection of mine audio electrical perspective.
