    摘要:

    为了准确计算矿井瞬变电磁场的磁场参数基于瞬变电磁场全空间和半空间研究理论研究矿井瞬变电磁场磁场强度与半空间瞬变电磁场磁场强度的关系提出矿井瞬变电磁场的倍数现象并在矿井中进行探测应用。研究结果表明全空间瞬变电磁场磁场强度与半空间瞬变电磁场磁场强度存在倍数现象即早期存在2倍的关系晚期存在2.5倍的关系延伸矿井瞬变电磁场磁场强度、电场强度、视电阻率计算也存在一定的倍数关系倍数现象的提出对研究矿井瞬变电磁场在理论和实践上具有重要的参考价值。

    Abstract:

    In order to accurately calculate the magnetic field parameters of mine transient electromagnetic field based on the former research theory of transient electromagnetic field full-space and half-space combined with transient electromagnetic space applications in mines this article studies the relationship of transient electromagnetic field intensity and half-space transient electromagnetic field and proposes the multiple phenomenon of transient electromagnetic. Research results show that full-space transient electromagnetic field intensity and half-space transient electromagnetic field intensity has multiple phenomenon. They have 2 times relationship in the early stage and have 2.5 times relationship in the late stage. Similarly mine transient electromagnetic field intensity electric field intensity and apparent resistivity calculations also have multiple relationships. Putting forward the multiple phenomenon has important reference value in theory and practice for researching the mine transient electromagnetic field.
