【摘要】 结合矿井全空间瞬变电磁法在山西郭家山矿巷道超前探水中的实际应用,在相同空间环境下采用多方向对比优化探测方案,并建立相应的全空间消噪数学模型,利用消噪函数对探测数据进行消噪归一化处理。研究结果表明:全空间电磁消噪归一化后,更能突出探测区域存在的异常差异,进一步提高了探测结果解释的准确性和可靠度,对井下超前预测及安全生产具有重要的指导意义。更多还原

【Abstract】 In combination with the actual application of the mine full space transient electromagnetic method to the advance water detection of a mine roadway in a mine of Shanxi,in a same space environment,a multi directional comparison optimized detection plan was applied,a related full space denoising mathematics model was established and the denoising function was applied to the normalization processing of the denoising for the detected data.The study results showed that after the normalization processing of the full space electromagnetic denoising conducted,the abnormal differences existed in the detection region would be more obvious,the accuracy and reliability of the detection results explanation could be further improved and could have the important guidance significances to the advance detection and the safety production in the underground mine.更多还原
