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
The present invention relates to for the two electrical survey (-ing) instruments in a kind of ground of ground location technology, utilize this instrument can all kinds of solids of Underground and liquid mineral reserve.
Technical background
Existing ground electrical survey (-ing) instrument, as U.S. V8 multifunctional digital electrical prospecting apparatus, the ATEM-II of Chongqing Geological Instrument Factory type electrical survey (-ing) instrument etc., basic principle is to gather resistance parameter and induced polarization parameter by watt current.External instrument is expensive, and domestic instrument exists investigation depth deficiency, it is not enough and because measuring the excessive range of application of electric current limited three large defects to survey accuracy rate.
This project team, through research for many years, has grasped the two electrical survey (-ing) technology of ion-conductance capacity rate Detection Techniques and capacitivity/resistivity.When ion-conductance capacity rate Detection Techniques are used separately, can there is the identity function that resistivity is surveyed, can also partly make up the deficiency of resistivity Effect on Detecting.Two electrical survey (-ing) technology can be calculated the parameters such as moisture content/salinity, can sxemiquantitative provide moisture volume with long-pending containing ore body.In two electrical survey (-ing) theoretical foundation, can develop water detector that function is more good, mine locator, the permeable early-warning apparatus in colliery etc. and survey new equipment.
Summary of the invention
The object of the invention is in order to overcome the deficiencies in the prior art, provide a kind of ground two electrical survey (-ing) instruments, survey for solid or liquid mineral reserve, change to reflect the feature of underground mine by measuring the resistivity on stratum and this biparametric of capacitivity.
Technical scheme of the present invention is:
The two electrical survey (-ing) instruments in a kind of ground of the present invention, mainly comprise that outdoor high power lithium power supply, signal generator, measuring circuit, signal storage circuit, inert electrode, GPS module, data processing module, image display, mineral reserve evaluation module form.Provide power supply by outdoor high power lithium power supply to instrument, produce medium and low frequency AC signal by signal generator, measuring circuit is measured respectively through two electrode stream to testee watt current and reactive current, be converted to again resistivity and the capacitivity signal of testee through measuring circuit, preserve survey data through signal storage circuit, meanwhile, produce coordinate information by GPS, and record the geodetic coordinates of survey mark.Measured data carry software through instrument and carry out data processing, and the image of the testee obtaining after image display shows well data transaction, and provide the evaluation result of tested region mineral reserve.
Advantage of the present invention and innovative point are: measure resistivity and the capacitivity of testee in medium and low frequency section simultaneously, and directly provide mineral reserve evaluation result; This instrument can improve investigation depth, improves its resolution ratio, and instrument volume is little, easy to carry.
