Abstract

The invention provides a surrounding rock stress detection method and device and electronic equipment. The method comprises the steps of determining an undisturbed region and a disturbed region in a to-be-detected region; performing electromagnetic wave CT detection on the undisturbed region to obtain an initial first electromagnetic wave image, and performing electromagnetic wave CT detection on the disturbed region to obtain an initial second electromagnetic wave image; performing electromagnetic wave attenuation coefficient anomaly detection on the initial second electromagnetic wave image according to the initial first electromagnetic wave image, and marking an abnormal position on the initial second electromagnetic wave image when determining that the abnormal position exists so as to generate a middle second electromagnetic wave image; and generating a surrounding rock stress detection result corresponding to the to-be-detected area according to the initial first electromagnetic wave image and the middle second electromagnetic wave image. The surrounding rock stress is detected based on the electromagnetic waves, so that the detection process is simpler and quicker, and meanwhile, the detection precision is ensured.

Description

technical field [0001] The present application relates to the technical field of coal mining, in particular to a detection method, device and electronic equipment for surrounding rock stress. Background technique [0002] Coal is the main energy source in our country, and has played an important role in promoting the 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 in the coal mine stope is one of the main research directions. [0003] In related technologies, fiber-optic grating drilling stress detection, microseismic monitoring, and geoacoustic monitoring are usually used to detect surrounding rock stress in coal mine stope...
