Abstract

Abstract In the process of tunneling, it is crucial to explore the geological body before excavation. The three-dimensional direct current method has been widely used in mining working face exploration for its advantages of strong anti-interference ability, simple operation, and without the blind zone. However, the direct current method's advanced detection has not been widely used, resulting in difficulties with the immature theory and data processing. In this paper, Based on the spherical shell theory, ANSYS realizes the forward modeling of direct current method advanced exploration and analyzes the feasibility of different arrays in advanced roadway exploration in the roadway. The research results show that the location of the shallow low-resistivity geological body can be accurately obtained by the least square inversion(by RES2D) of the correction data through the joint application of various arrays, and the three-dimensional direct current method based on the spherical shell theory is feasible for advanced exploration in the roadway.
