Exploration device and exploration method with novel high-density electrical method or ultra-high-density electrical method

Abstract

The invention discloses an exploration device with a novel high-density electrical method or ultra-high-density electrical method. The device comprises a master controller, a current generator, a signal detector and a non-grounded electrode array. The master controller controls the current generator to generate a current signal, controls the non-grounded electrode array to operate and receives a signal of the non-grounded electrode array detected by the signal detector. The current generator generates the current signal and loads the current signal to the non-grounded electrode array. The signal detector detects an electrical signal in the non-grounded electrode array and uploads the electrical signal to the master controller. The non-grounded electrode array receives the current signal and couples the current signal into the ground or receives an electrical signal coupled from the ground. The invention also discloses an exploration method with the novel high-density electrical methodor ultra-high-density electrical method. The burying of an electrode is not needed and bus control is used, the measurement range is extremely wide, a measured target object is not damaged, the multi-dimensional measurement with a large pole pitch, a large depth and multiple devices can be achieved, and a measuring device is simple and reliable.

Description

technical field [0001] The invention specifically relates to a novel high-density electrical or ultra-high-density electrical exploration device and exploration method. Background technique [0002] High-density electrical method is a common geophysical prospecting method. It is based on the difference in electrical properties of rocks and ores, and solves problems in hydrology, environment and engineering geology by observing and studying the distribution of artificially established stable electric fields. The high-density electrical method uses electrode arrays for electrode layout and observation, and can obtain rich geological exploration data in a multi-channel manner, greatly improving the applicability, reliability and accuracy of exploration. [0003] However, the traditional high-density electrical method has the following problems: (1) The measurement efficiency is low by burying electrodes; (2) In engineering exploration, there are many occasions where electrodes ...

Problems solved by technology

[0003] However, the traditional high-density electrical method has the following problems: (1) The measurement efficiency is low by burying electrodes; (2) In engineering exploration, there are many occasions where electrodes are not allowed to be buried; (3) In the case of high surface resistance, the high-density electrical method has poor measurement effect and shallow exploration depth

[0004] Therefore, the current traditional high-density electrical prospecting devices and prospecting methods have relatively large limitations, and the application effect is poor in specific occasions
