A method for analyzing and controlling dynamic deterioration evolution of anchoring body under impact condition of coal mine

Abstract

The present application relates to the technical field of coal mine engineering rock mass support, in particular to a coal mine anchoring body dynamic deterioration evolution analysis and control method, device and computer storage medium, comprising the following steps: arranging a backscattering holographic observation system and a multi-axis stress imaging array on the boundary of the roadway, collecting shock wave global propagation response information, and generating a boundary reflection spectrum; based on the boundary reflection spectrum and the original stress field characteristics, a phase amplitude coupling model is constructed, a reverse stress amplification prediction interval is derived, and a limit overload sensitive area is identified. The present application constructs a multi-field sensing and phase coupling analysis mechanism, accurately identifies the shock wave propagation path and stress amplification area, combines time reversal detection and bond spectrum inversion, realizes early deterioration diagnosis of the anchoring body, and constructs a dynamic closed-loop control path through impedance regulation and phase traction, significantly improving the impact resistance of the coal mine anchoring system and the disaster prevention and control level.
