摘要
介绍了矿井瞬变电磁井下探测金属体干扰因素,分析了干扰校正的技术方法,利用模型模拟计算在不同情况下矿井瞬变电磁的响应信号,运用矿井瞬变电磁干扰校正方法对有干扰的信号进行分析并校正,得到接近于无干扰情况下瞬变电磁响应数据,通过对实测数据的处理以及与现场验证的的对比,证明了该校正方法的可靠性与有效性。
The mine transient electromagnetic detection of underground metal body interference factor analysis method,interference correction,using the model simulation of mine transient electromagnetic response signals in different situations.Electromagnetic interference with mine transient correction method to analyze signal interference and correction,get close to no interference under the condition of transient the electromagnetic response data,by processing the measured data and verify the contrast with the scene,to prove the reliability and validity of this calibration method.
