| Abstract: |
| Taking the coal and gas outburst as a complex system, the mechanism of coal and gas outburst is analyzed by applying the catastrophe model of system theory. Taking the surrounding rock stress and strain as control parameters and the mining activities as state parameters, the changing regulation of coal and gas outburst parameters is studied to provide parameter foundation for the theoretical research of coal and gas outburst and the determination of experimental programs. |
