摘要
瞬变电磁法常用来查明含水地质体,如岩溶洞穴导水通道、煤矿采空区、不规则水体等,具有自动消除主要噪声且地形影响较小、分辨能力强等优点。本文设计了基于FPGA控制的矿井高分辨率瞬变电磁探测系统,该系统具有采样频率高,动态范围大,工频抑制能力强等特点。
Transient electromagnetic is often used to find out the water-bearing geological body,karst caves,coal mine goaf water channels,such as irregular water body,etc.,with automatic eliminate noise and topography,a smaller effect,strong resolution,etc.This paper was designed based on FPGA control mine high resolution of the transient electromagnetic detection system,the system has high sampling frequency,wide dynamic range,the characteristics of power frequency suppression.
