Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Fractal geometry is used in many fields such as medicine, communication, computer, etc., aiming to find order in chaos. Fractal dimension is the most important parameter to describe fractal, using the method of dimension to explain the spatial state of objects. Due to the limitations of the calculation method, the calculation results often deviate, which hinders the conclusio...

Abstract

The invention provides a microseismic event space-time fractal dimension calculation method and device and electronic equipment. The method comprises the steps that: a clustering analysis result of a microseismic event is obtained; an ellipsoid calculation total model and ellipsoid calculation sub-models corresponding to different time periods are determined based on the clustering analysis result, wherein the time periods are divided based on working conditions and blasting time, and the parameter proportions of the ellipsoid calculation sub-models are the same as the parameter proportion of the ellipsoid calculation total model; and the time-space fractal dimension of the microseismic event is determined based on the ellipsoid calculation total model and the ellipsoid calculation sub-models. According to the method, quantitative calculation of the time-space fractal dimension of the microseismic event can be achieved, law summarization and mechanism analysis of dynamic disasters such as rockburst are facilitated, and prediction and early warning are achieved.

Description

technical field [0001] The invention relates to the technical field of mine safety, in particular to a method, device and electronic equipment for calculating the space-time fractal dimension of microseismic events. Background technique [0002] Fractal geometry is used in many fields such as medicine, communication, computer, etc., aiming to find order in chaos. Fractal dimension (fractal dimension) is the most important parameter to describe fractal, using the method of dimension to explain the spatial state of objects. In the relevant microseismic ground pressure monitoring reports, almost no fractal dimension is used to describe the spatiotemporal evolution of microseismic events. Contents of the invention [0003] In view of this, the object of the present invention is to provide a method, device and electronic equipment for calculating the space-time fractal dimension of microseismic events, which can realize the quantitative calculation of the space-time fractal di...
