Abstract

In-well IP is one of the effective means to explore deep sulfide-type metal ore. In the well, the electric field-well method is used to find the bottom of the well and the blind mine near the well; in the well, the electric well-ground method is used to determine the ore body’s direction and judge its occurrence. The exploration examples of the Beiwopu copper deposit in Inner Mongolia indicate that the ground-well IP measurement corresponds to high polarization anomalies in the pyrite-rich and brass mineralization-enriched rock sections; the well-ground charging method is used to measure the occurrence of ore bodies. Judging, retrieving the direction of the ore body, guiding the drilling project, reducing the investment in exploration, and achieving A better prospecting effect.

Key words： in-well excitation well-ground charging profile concealed copper ore deposit attitude
