Problems solved by technology

However, the above methods can only conduct empirical and qualitative analysis on the distribution of dangerous areas and their grades, and the evaluation results depend on the authenticity and completeness of the mine's data on the evaluation area before mining, and also on the knowledge and knowledge of the evaluators. Professional level
Due to the complexity, variability, and insufficient exploration of coal mines, the evaluation results often have large deviations from the actual situation, which seriously affects the pertinence and effectiveness of rock burst prevention and control.

Abstract

The invention provides an impact risk static evaluation method and system combining theoretical analysis and on-site CT detection, a storage medium and computing equipment. According to the method, the method comprises the following steps: dividing factors influencing rock burst into global factors and local factors; establishing approximate linear relations between each influence factor and an impact risk, performing normalization processing and superposition to obtain a global impact influence index and a local impact influence index, and superposing the global impact influence index and thelocal impact influence index to obtain a theoretical evaluation impact risk index. In addition, theoretical evaluation and on-site CT detection results are superposed to determine the static danger distribution and grade of the target area. Based on the method provided by the invention, the scientificity and accuracy of impact risk assessment before mining are remarkably improved, and the treatment work of various rock burst disasters in the mining process can be more effectively guided.

Description

technical field [0001] The invention relates to the technical field of mine monitoring, in particular to a static impact risk assessment method and system, a storage medium and a computing device combining theoretical analysis and on-site CT detection. Background technique [0002] As a pre-mining impact risk assessment, the static impact risk assessment can grasp the impact risk degree of the area to be mined and the distribution characteristics of the dangerous area as a whole, and provide information for mining design, monitoring system layout, prevention and control plan formulation, and personnel management. The basis is an important part of the prevention and control of rock burst disasters. [0003] At present, the methods used for static assessment of impact risk mainly include: comprehensive index method, multi-factor coupling method, dynamic zoning method, possibility index method, quantitative theory method, dynamic weight method, etc. However, the above methods ...
