| 摘 要： | 本文首先给出在水平覆盖层条件下采用沉降电极纯异常供电系统时沿地表主剖面上由基岩中埋藏的球状矿体所产生的异常磁场表达式,继而给出任意厚度覆盖层具有不同导电性能的异常磁场计算结果,并对异常的分布规律进行了系统分析。得出了,在低阻覆盖层条件下寻找深部盲矿时,采用沉降电极磁电法具有充分的理论基础,而采用在地面上的供电系统是无能为力的。

| Abstract: | This paper first gives the expression for anomalous magnetic field produ ced by spherical orebody buried in bedrock along the surface peincipal profile under the condition of horizontal cover with the adoption of receiving electrode pure anomaly feed system, then gives calculations for anomalous magnetic fields with different electric conductivities under covers of any thickness, and also makes a systematic analysis of the distribution of anomalies. Finally, it is concluded that in prospecting for blind orebodies at depth under the condition of low-resistance cover, the adoption of receiving electrode magnetic-electric-method can theoretically hold water, whereas the surface feed system will surely be useless. |
