2D Imaging Geophysical Exploration Instrument for Metal and Water Detection
Electrical exploration is a geophysical exploration method to find different types of useful mineral deposits, identify geological structures and solve geological problems by observing and studying the spatial distribution and temporal characteristics of artificial or natural electric fields, electromagnetic fields or electrochemical fields according to the differences of electromagnetic properties (such as conductivity, magnetism, dielectric) and electrochemical characteristics of various rocks or orebodies in the crust.
Applications
The geophysical exploration instrumetn can be used in energy exploration and civil geophysical prospecting, railway and bridge survey, mental and non-mental mineral survey. This geophysical instrument can also be used in hydro- and engineering geology survey, such as underground water, water reservoir dam site, flood control dam hidden trouble detection, and geothermic field survey.
Electrode arrangement
Up to 18 types of devices are extensible. It can be scanned according to fixed section (electrode arrangement is AMNB, ABMN, AMBN, AMN, MNB, A-Mn-B, self-charged M, self-charged MN, charging M, charging MN) and continuous rolling scanning measurement according to variable section (electrode arrangement is A-M, A-MN, AB-M, AB) -MN, MN-B, A-MN rectangle, A-Mn-B, cross-hole dipole), among which, continuous rolling scanning measurement can allow the measurement section to be connected to any length under the condition that the total number of electrodes is unchanged, which is convenient for long section tracking, enabling users to solve practical problems at low cost and high time.
