Technical Specifications

CASE：MT+TDLP

In a mining area in Northwest China, the induced polarization method and magnetotelluric method are used for joint exploration. The same set of equipment collects data at the same time and at the same points, so as to improve the acquisition efficiency, and complete large depth + shallow high-resolution exploration at the same time. The induced polarization method has very high resolution in the shallow part, and can obtain the full waveform polarizability data, which can clearly reflect the underground electrical characteristics within 600m; The deep exploration by magnetotelluric method reflects the deep rock mass and structural characteristics. Combined with the shallow IP section, the underground electrical structure can be inferred more comprehensively.

Construction method:TDIP bilateral three pole,50m point distance;MT vector measurement, 200m track distance.

CASE：MT

In the detailed magnetotelluric survey of the structural development section of Gaoligongshan tunnel of Darui railway, the terrain within the survey line is seriously cut and the vegetation is dense. Node distributed acquisition is adopted to give full play to the advantages of ultra-small volume of equipment and improve the acquisition efficiency. The exploration depth is 1000m, and the electrical characteristics of magnetotelluric profile are basically consistent with geological and borehole data. The spatial characteristics of geological inferred faults in the deep are revealed, and the electrical characteristics of surrounding rock in multiple lithologic interfaces and tunnel elevations are found out.

Construction method: MT vector measurement, acquisition time 2 hours, electric track distance 20-40m, magnetic track distance 100m.

CASE：Active Source Sesmic and HVSR

Q1: what is the uniqueness of both compared with traditional geophysical equipment?

The node unit contains 3 (2 ~ 4 optional) 32-bit high-precision acquisition channels, which are compatible with sensors of different types and manufacturers. After the field layout is completed, electromagnetic method, three-dimensional induced polarization method and active source / passive source seismic data acquisition can be carried out at the same time. In one layout, multiple geophysical parameters can be collected to facilitate the simultaneous construction of multiple methods.

Q2: what scenario is suitable for using the both system?

1. Work areas requiring shallow high-resolution and deep electrical information measurement

2. Work areas where the interpretation accuracy of single method is not enough and comprehensive verification of multiple methods is required

3. Large area three-dimensional induced polarization exploration mining area

4. Complex terrain and low efficiency of conventional construction equipment

Q3: why is it efficient?

1. A variety of geophysical parameters are obtained in one layout, which solves the problems of equipment replacement and repeated construction in different methods; Any combination of magnetotelluric, induced polarization method and seismic method;

2. The node layout mode is adopted, and the weight of a single host is light. More than 12 sets can be operated by a single person in the field, and the pole layout efficiency is several times better than that of traditional instruments.

Q4: how to deal with the collected multi parameter data?

Equipped with special data preprocessing software rocket, it integrates earthquake, three-dimensional induced polarization method, frequency domain induced polarization method and electromagnetic method, and can efficiently manage the original data, preprocess the data and input and output the data. The main functions of the software include: original time series management, data inspection, time domain filtering and preprocessing, three-dimensional layout design, induced polarization data fusion, IP attenuation curve extraction, amplitude and phase extraction, seismic data preprocessing and inspection, seismic data extraction, section display, etc.
