Research on the method and technology of magnetic prospecting method using V8 systems

During the electrical prospecting on the shallowed coverage area, Due to the supply current is easily absorbed by the low resistance coverage and deep electromagnetic signals are shielded weakened, Thin layer metal ore difficult to be identified. Based on breakthrough high resistance and low resistance layer shielding cover to obtain effective ore induced signal of ideas, We carry out the magneto electric prospecting method experimental study. Using V8 system and other instruments to complete the work of launching and receiving. The magnetic field and electric potential generated by the alternating electromagnetic field of different frequency to the excitation of the ore bodies are measured respectively. Calculate the magnetic dispersion rate and the electric dispersion rate. Extracting and comparing the local anomaly information to identify the ore bodies. A certain effect has been achieved in the identification of thin ore bodies in a gold deposit in Anhui Province, Which has extended the application range of V8 system in geological prospecting.
