Main application:

• Metal ore, non-metal ore and underground water general survey.

• City prospecting, engineering exploration like railway &bridge, resistivity imaging survey of archeological mining and geological structural mapping etc.

• Hidden faults in dikes detect, such as high resolution prospecting of ants-nest &rat hole of river levees, weak intercalation and fracture.

• Geological exploration in hydrology, engineering, environment and high resolution resistivity method engineering

•  Detect of coal goaf, civil air defense works and cavities in karst area. Also geological disaster of factory foundation, highway, bridge, railway and landslide etc

 

Main features:

 

1.High resolution and high efficiency electrical prospecting: The system consists of two parts: DZD-6A multi-function DC resisitivity meter and the multiplexor. It is used to explore matching with the high-new technology such as CT and auto conversion measure and supply of electrodes based on the theory of regular resisitivity methods.

 

2.Time domain DC resisitivity method and IP method: DZD-6A multi-function DC resistivity meter can be solely employed to perform resisitivity and IP survey under conventional modes. There is many parameters in this mode: spontaneous potential (Vsp), primary field potential (Vp), supply current (I), apparent resisitivity RO(ps), apparent polarizablility (M1-6), half-life time (Th), degree of damping (D), synthetic excited electron parameter (Zp) and degree of deviation (R).

 

3.More flexible and convenient operation method: It can auto-compensate self-potential, drifting and electrodes polarizing by employing full digital auto-measurement. Results are displayed on large LCD screen which can list more than 14 kinds of array modes under resistivity imaging survey. In DZD-6A's single mode it can display 9 electrode arrays and measured curves timely as well.

 

4.Convenient data explanation: a. It can store data up to 120000 points in resistivity imaging survey mode. b. It stores data of 4800 points in DZD-6A single mode, and each point includes 22 figures. Data can be directly transmitted to a PC for digital explanation by corresponding software.
