摘要
文章介绍了利用天然电磁场进行勘探的方法原理,简述了该仪器在软、硬件二次开发后进行水资源、矿产资源勘探的试验对比。结果表明,改进后的仪器有效测频范围为200Hz～100kHz,勘探深度达400～500m。
The paper introduces the secondery development of soft and hardware of the natural electroma-gentic depth detection instrument. Rusults of the seconderily developed instrument for water and mineral resources exploration are better than that of the original. The depth detection is up to 400～500 m with the efficient frequency range of 200 Hz～100 kHz.
