Embodiment Construction

[0044] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail;

[0045] The invention provides a coal mine rockburst prediction method based on AHP and fuzzy comprehensive evaluation, which is divided into the following steps: figure 1 shown in the following steps:

[0046] S1: Based on the basic statistical analysis of rock burst disasters that have occurred, determine the set of evaluation factors U=(u 11 , u 12 , u 13 , u 14 , u 21 , u 22 , u 23 , u 24 , u 25 , u 31 , u 32 , u 33 , u 34 , u 35 , u 36 ), according to field tests, geological data analysis, mine design related data to obtain the value of each evaluation factor;

[0047] According to the judging factors that affect the occurrence of rock burst, the geodynamic and environmental factors U 1 , geological factors U 2 and mining factor U 3 ; Among them, geodynamic and environmental factors U 1 Including structu...

Abstract

The invention discloses a coal mine rock burst prediction method based on analytic hierarchy process and fuzzy comprehensive evaluation, relates to the technical field of mine safety production, and aims to analyze, screen and consider the influence of multiple factors such as geological dynamic environment, geology and mining on rock burst danger. Secondly, each factor is endowed with a respective corresponding weight according to different influence degrees, a fuzzy relation matrix is jointly formed by combining the membership degrees of the factors, and the rock burst danger is predicted by adopting a fuzzy comprehensive evaluation method, so that the computability and quantifiability of the rock burst danger degree are realized; and meanwhile, the rock burst danger is divided into different grades, so that the method is more detailed and reasonable compared with the traditional two-stage method with impact and without impact, and the rock burst prevention and control work can be more targeted and effective.

Description

technical field [0001] The invention relates to the technical field of mine safety production, in particular to a coal mine rockburst prediction method based on hierarchical analysis and fuzzy comprehensive evaluation. Background technique [0002] Rockburst refers to a dynamic phenomenon of sudden and violent destruction of coal and rock mass due to the instantaneous release of elastic energy in the coal mining space. destructive. In recent years, the safety situation of my country's coal mines has been improving day by day, but several large and major rock burst accidents have occurred one after another. According to incomplete statistics, as of 2019, there were more than 180 rock burst mines in my country, mainly distributed in 25 provinces including Shandong, Henan, Heilongjiang, Shaanxi and Shanxi, almost all over the major coal mining areas, and rock bursts caused Secondary disasters such as large-scale collapse of roadways, casualties, equipment damage, and induced g...
