DEVICE FOR ELECTRICAL RESISTIVITY SURVEY AND METHOD OF ELECTRICAL RESISTIVITY SURVEY IN USING THE SAME

摘要

PURPOSE: A resistivity survey apparatus and a resistivity survey method using the same are provided to save drilling costs and survey time by not requiring electrode attachment or a drilling hole for resistivity survey in an outcrop. CONSTITUTION: A resistivity survey apparatus(1) consists of a potential difference measurement unit(2) and a resistivity calculation unit(3). The potential difference measurement unit measures potential difference about an underground medium by contacting to the surface. The potential difference measurement unit consists of a body unit(100), an electrode unit(200), a connector(300), an electrolyte supply unit and an electrolyte storage unit. The electrode unit flows current through the underground medium and measures difference of potential vertically formed in the path of current. The connector is installed in one side of the body unit and is connected to the resistivity calculation unit. The electrolyte supply unit is installed in an inside of the electrode unit. The resistivity calculation unit is electrically connected to the potential difference measurement unit and calculates resistivity from the potential difference measured in the potential difference measurement unit.
