Abstract:This paper has first analyzed the disturbance type which in the mine pit survey meets, the union noise signal characteristic, proposed based on the electromagnetic induction mine pit survey method, has produced its schematic diagram and the principle of design. Then in detail elaborated the electromagnetic induction survey method concrete realization, has produced each main test parameter formula, has been clear about each kind of signal which needs to gather in the survey process. In order to confirm the electromagnetic induction survey method which proposed, finally used MATLAB to establish the simulation test model, and has produced the simulation test result.
