The development of coal mine intelligence provides new perspectives for enhancing mine safety assurance capabilities. However, research on the perception method of coal mine disasters is still insufficient, and it is difficult to effectively perceive the stage of disaster development, and then the prevention and control measures taken are not targeted to the stage of disaster development. To address these issues, this paper proposes a coal mine disaster perception method based on the analysis of disaster evolution characteristics. By studying the development mechanism of mine disasters, the evolution stages of disasters are delineated, transition conditions of each stage are identified, and controlling factors are recognized. Combining correlation analysis methods, sensitive indicators are selected for perceiving the stages of disaster development. Using the coal mine water inrush accident triggered by fault activation as an example, experimental verification of the disaster perception method is conducted. The results indicate that sensitive characteristics reflecting the degree of evolution of the fault activation water inrush accident vary with the advancement of the working face. Therefore, perception methods based on evolutionary feature analysis hold promise for providing reference for perceiving the stages of coal mine disaster development.
