Product Description
1.Overview
Natural electric field frequency selection method, referred to as frequency selection method. It is based on the differences of electrical properties of mineral rocks underground, through measuring the natural frequency magneto telluric election (Frequency 0.n-30 kHz), and according to the regular variation of different frequencies of electromagnetic fields, to research the situation underground, it is an alternating current exploration methods, in order to solve geological exploration problems. The instrument is Natural Electric Field Frequency Selection Geophysical Measuring instrument (Frequency Selection Instrument)
Frequency Selection Instrument is mainly used in cities, mountains and plains to quickly find and analyze groundwater (e.g. magma tic water, bedrock fracture spring, quaternary and tertiary phreatic water). To solve geological problems, such as to find and identify the natural or artificial caves (e.g. natural caves, soil cave, tomb, bomb shelters, Coal Mine, coal mine water inrush); to find the fault under the cover and fracture zone; stability analysis of building foundation; find and identify objects buried underground (e.g. water pipes, gas pipes, cast iron or concrete pipes, cables); to find quartz vein or fracture zone goldmine, and so on. Practice has proved Frequency Selection Instrument has received significant geological effects in solving the above geological problems.

3. Introduction of instrument works
UG-02 Mine Locator exploration method is Natural Electric Field Frequency Selection Geophysical Measuring Method, it is using Magneto telluric as working electromagnetic field source, based on ground resistivity differences between rocks and minerals, and research electrical changes of underground geoelectric section according to several or dozens of different frequency variations of the electric field component, which is Alternating Current Geological Exploration Methods. Because the electric fields measured are magneto telluric electrical components, it is called Natural Electric Field; and because when operating the instrument selects several or dozens of low-frequency electric field component as measurement parameter, then it is named Frequency Selection Method; and the exploration method is named Natural Electric Field Frequency Selection Method.
Magneto telluric Signal is Input to Impedance input stage by IN (A/B) electrode probe (sensor) via cable, after attenuation Alternating Current is enlarge, and frequency selection, select the required operating frequency signal, and then after AC-DC converter A/B sampling and CPU data processing (e.g. anti-Interference data processing). In the course of the entire operation, under the control of CPU, the instrument is automatic range switching and automatic frequency selection. Finally, measurements are showing on the LCD screen. Analyze depending on the anomaly curves and measurement data to make geological conclusions.
About formula
First, through complex mathematical equations, convert Maxwell Equations to passive region wave equation, find periodic particular solution, then calculate the penetration depth of electromagnetic waves ( d=503.5 r f the relationship among δ Electromagnetic penetration depth, ρ Medium Resistivity and f frequency). Then through complicated mathematical calculations, obtain the relationship between wave impedance and medium resistivity. Treatment the same as resistivity, resistivity measured in the field is called apparent resistivity, finally convert to r ~ = 2 apparent
S1 Ex( )2 5 f Hy resistivity and impedance, frequency and the formula. The two formulas are basic formulas of Natural Electric Field Frequency Selection Method.
Formulas
Formulas:
d=503.5 r (f 123)
δ:Penetration depth of electromagnetic waves (m) ρ:Homogeneous medium resistivity (Ω-m)
f:Operating frequency: measuring frequency of instrument, UG-02 operation frequency is 25c/s, 67c/s, 170c/s , and 30 frequency of multi-frequency measurement.
Formulas Analysis
How deep can electromagnetic waves penetrate? According to the relationship among δ, ρ and f, the penetration depth is decided by the ρ and f. Learn formulas:
1. When underground resistance ρis fixed number, the higher operation
frequency f,the more shallow electromagnetic waves penetration depth δ. The lower operation frequency f (low frequency), the more deep electromagnetic waves penetration depth δ. So when underground resistance ρ is fixed number, it is better to select low frequency f for operating.
2. When operation frequency f is fixed number: The larger underground resistance ρ (no electrical conductivity), the more deep electromagnetic waves penetration depth δ (not absorb).
The lower underground resistance ρ (electrical conductivity), the more shallow electromagnetic waves penetration depth δ (absorb).
Formulas:
~ rS= 1 5f(Ex Hy)2(1-34) ~ r
S:: Apparent Resistivity, Ohm-meter (Ω-M)
f:Operation frequency f (Hertz c/s) Ex:Electromagnetic field strength of x direction (Mill volt/kilometer, Mv/ KM) Hy: Magnetic field intensity of y direction (Gamma r)
Notes:
1. Finish operation, make sure record the exploration data, and do remember to turn off the instrument.
2. If instrument does not work, maybe there is not enough power, please charge; and the printer is also charged regularly.
3. Plug of the probe cable must be kept dry; it must not be kept in high-temperature environment, if the plug is damp or kept in high-temperature environment, the sensitivity will reduce greatly, and influence the exploration effect.
4. Keep the instrument in clear and dry environment; prevent a short circuit or equipment corrosion.
5. Avoid the instrument suffered severe vibration or impact.
6. Free repair during the warranty period according to warranty card. If user disassembles instrument or changes wire lines, the factory is not responsible for repairing.
7. Analyze the wave lines
We give an example exploration group P01 to analyze the wave lines of Ch1, Ch2 and Ch3. Ch1, Ch2 and Ch3 wave lines are formed according to three solid signal frequencies, which has been settled in internal procedures of UG-02 Mine Locator by professional doctors. And we can analyze according to the example of finding water well underground.
The exploration group P01 three wave lines Ch1, Ch2 and Ch3. You can find Time5 position and wave line shape of Ch1, Ch2, Ch3 is most similar, then that means Time5 position on the ground is the water well.
