Abstract
A method for detecting a stress state-of rocks surrounding a roadway based on three-dimensional electric potential response is disclosed. By collecting electric potential data, and performing spatial interpolation on all the electric potential measurement points to obtain a three-dimensional electric potential imaging volume, three-dimensional electric potentials can be used to draw electric potential isosurface models. By using a radial basis function surface interpolation method to draw a three-dimensional abnormal electric potential inversion probability isosurface model, it is possible to intuitively visualize electric potential distribution spatial characteristics of rocks surrounding a roadway, so as to clearly display a spatial range, direction and development trend of abnormal stress zones, and accurately identify and determine the stress states of roadway rock formations.
