The essential of coal and rock dynamic catastrophe is the self-organizing critical process of energy accumulation and dissipation.If the elastic energy accumulatedin coal and rock mass reaches the critical burst energy,rock burst will happen.According to experimental researches,elastic and brittle coal mass is the main-body of energy accumulation and dissipation,the movement of key roof stratum(the hard thick sandstoneroof) can cause accumulation and dissipation of energy tolose dynamic… Expand
Deformation Rules for Surrounding Rock in Directional Weakening of End Roofs of Thin Bedrocks and Ultrathick Seams
With the deployment of China’s energy strategy in the western regions, complex geological mining conditions such as thin bedrock and ultrathick seams in western China have caused a series of problemsExpand
