摘要
瞬变电磁法由于采用的是不接地的回线观测纯二次场,适合在沙漠地表条件下工作,有较高的工作效率。利用中心回线装置观测,可达到与探测目标的最佳藕合,取得的异常强、形态简单、分层能力强,利用其对低阻异常反映灵敏的特点探测金属矿效果明显。实际证明,瞬变电磁法配合高精度磁测和激电测量等进行多参数多方法探测隐伏金属矿是切实有效的。
As a result of the TEM is not grounded back to the pure secondary field line observation, suitable for under the desert surface conditions, and higher efficiency. Using observations of central loop device is up to the best coupling with the probe target, nmkes abnormally strong, simple forms. Layered ability to use its low resistivity anomaly reflects the characteristics of sensitive detection of metal mines significantly. The actual proof of TEM with high-precision magnetic measurement and laser power measurement method for muhi-parameter detection of multi-metal mine is effective.
