Title:
ROADWAY SURROUNDING ROCK STRESS STATE DETECTION METHOD BASED ON THREE-DIMENSIONAL POTENTIAL RESPONSE
Document Type and Number:
WIPO Patent Application WO/2024/046501
Kind Code:
A1
Abstract:
Disclosed in the present invention is a roadway surrounding rock stress state detection method based on three-dimensional potential response. The method comprises: collecting potential data of each potential measurement point in a drill hole; then, spreading a roadway contour as a plane along a side line of the strike of a roadway; performing spatial interpolation on all potential measurement points, so as to obtain a three-dimensional potential imaging body, and extracting and drawing a three-dimensional abnormal potential isosurface model; and performing unilateral inversion on an outer side of a drilling area by means of potential measurement points on a potential measurement line at the highest position, and extracting and drawing a three-dimensional abnormal potential inversion probability isosurface model by using a radial basis function surface interpolation method. In the present invention, a three-dimensional potential response digital model, which is jointly formed by a three-dimensional abnormal potential isosurface model and a three-dimensional abnormal potential inversion probability isosurface model, visualizes spatial potential distribution features of roadway surrounding rocks, clearly presents a spatial range, a strike and a development trend of an area in which stress is abnormal, and accurately distinguishes and determines an area for roadway stress state and abnormal potential response.
