【摘要】 本文从常规电法入手结合危机矿山的具体环境,详细分析适应危机矿山勘探的方法原理及其适用性,最后总结出两种电法组合模式。在工程勘探的实际应用中说明效果良好。文中针对影响危机矿山勘探中,严重影响CSAMT解释结果的静态效应问题进行改正。文章从电磁基本理论出发,分析了静态效应的产生机制,采用瞬变电磁法与CSAMT联合反演校正静态影响。从对比处理结果中说明该方法优于常规空间滤波法,应用在危机矿山实测资料处理中取得了明显的效果。瞬变电磁的关断时间影响是制约其在危机矿山中应用的一个主要问题,文中针对此问题应用了一种直接数值校正方案,并用两种关断电流来模拟实际中的电流衰减。通过应用文中所述的方法,对甘肃北山地区的危机矿山实测资料校正后取得了明显效果。更多还原

【Abstract】 The paper researches from the conventional electric method and analysis’s specific environment of mine crisis, detailed description kinds of exploration theories and application. At last concludes tow kinds of combination electric models. From the actual application in the field, that it had good results.In the crisis the mine exploration, which has seriously affected the results of the CSAMT explain static effect to correct the problem. Articles from the electromagnetic basic theory, the static analysis of the effects of a mechanism, using TEM and CSAMT joint inversion correction static impact. Comparison of the results from the method is superior to conventional space filtering method, applied in the mine crisis in the measured data processing have achieved remarkable results.The off-time of TEM impact of the crisis is restricting its application in mining a major problem in the text on this issue, a direct application of numerical correction programmers, and in two shut down current to simulate reality in the current decay. Practical adopted the method described in the Gansu region in the northern mountains crisis measured data correction after the mine has achieved noticeable progress.更多还原
