The present application provides a method, device and electronic device for detecting surrounding rock stress. The method includes: determining an undisturbed area and a disturbed area in a to-be-detected area; and performing electromagnetic wave CT detection on the undisturbed area to obtain initializing a first electromagnetic wave image, and performing electromagnetic wave CT detection on the disturbance area to obtain an initial second electromagnetic wave image; according to the initial first electromagnetic wave image, performing abnormal electromagnetic wave attenuation coefficient detection on the initial second electromagnetic wave image, and When it is determined that there is an abnormal position, the abnormal position is marked on the initial second electromagnetic wave image to generate an intermediate second electromagnetic wave image; and according to the initial first electromagnetic wave image and the intermediate second electromagnetic wave image, generating The surrounding rock stress detection result corresponding to the to-be-detected area. The present application performs the stress detection of surrounding rock based on electromagnetic waves, which makes the detection process simpler and faster, and at the same time ensures the detection accuracy.
Description
technical field [0001] The present application relates to the technical field of coal mining, and in particular, to a method, device and electronic equipment for detecting surrounding rock stress. Background technique [0002] Coal is the main energy source in my country and has played an important role in promoting national industrial development and national economic progress. In recent years, with the rapid improvement of the intelligent level of mining equipment, the coal output of my country's coal mines has increased significantly. However, in the process of coal mine excavation, there are often many technical difficulties to be overcome. In particular, how to accurately detect the surrounding rock stress of coal mine stope is one of the main research directions. [0003] In related technologies, fiber-optic grating borehole stress detection, microseismic monitoring, geosound monitoring and other means are usually used to detect surrounding rock stress in coal mine s...
