Abstract

The invention relates to a ground dual-electrical-method detecting instrument used for the ground detection technology. The ground dual-electrical-method detecting instrument mainly comprises an outdoor high-power lithium power source, a signal generator, a measuring circuit, a signal storing circuit, a noble electrode, a GPS module, a data processing module, an image displaying module and a mineral resource evaluation module. The ground dual-electrical-method detecting instrument is powered on through the outdoor large-power lithium power source, low and medium frequency alternating-current signals are generated by the signal generator, the measuring circuit respectively measures an active current and a reactive current flowing to an object to be detected through two electrodes, and converts the active current and the reactive current into specific resistance signals and capacitivity signals of the object to be detected, the measured data are stored through the signal storing circuit and processed through software of the ground dual-electrical-method detecting instrument, an image, obtained after data conversion, of the object to be detected is displayed through the image displaying module, and the evaluation result of mineral resources in the area to be detected is given. According to the ground dual-electrical-method detecting instrument, the detection depth can be increased, the resolution ratio is improved, and the ground dual-electrical-method detecting instrument is small in size and convenient to carry.

Description

technical field [0001] The invention relates to a ground dual-electric method detection instrument for ground detection technology, which can detect various underground solid and liquid mineral deposits. technical background [0002] The existing ground electrical detection instruments, such as the American V8 multifunctional digital electrical instrument and the Chongqing Geological Instrument Factory ATEM-II electrical detection instrument, etc., are based on the basic principle of collecting resistivity parameters and excited polarization parameters through active current. Foreign instruments are expensive, and domestic instruments have three major defects: insufficient detection depth, insufficient detection accuracy, and limited application range due to excessive measurement current. [0003] After years of research, the project team has mastered the ion permittivity detection technology and the permittivity / resistivity dual electric method detection technology. When t...
