MECHANISM AND PREVENTION OF COAL ROCK DYNAMIC DISASTER IN COMPLEX GEOLOGICAL STRUCTURE AREA

After the coal mine enters the deep mine, the physical properties, stress, gas and other factors of coal and rock mass change significantly, the disturbance range and dynamic and static load of mining overburden increase significantly, the linkage disaster causing effect of mine groups and the control effect of large geological bodies appear, and the rockburst. The mutual transformation mechanism is unclear, and the lack of rapid detection means. The research direction of coal and rock power disaster prevention and control technology in deep mining is determined, and the multi-scale and source separation prevention and control theory and technical framework of coal and rock power disaster in deep mining are constructed. Finally, the multi-scale and source separation prevention and control theory and technical system of coal and rock power disaster in deep mining in China will be formed, which will provide a basis for rock burst Coal and gas outburst and composite coal and rock dynamic disasters provide theoretical support and technical ways for effective prevention and control.
