With the increasing of mining depth and mining scale day by day, the research on coupling occurrence mechanism and prediction technology of rock impact and outburst in the coal seam with high gas and high in-situ stress has become an important subject that should be to be solved urgently. The main influence factors of rock burst and coal and gas outburst are firstly analyzed in the paper, and then a mechanical model of coupling of burst and outburst is established with acme mutation theory. Based on this mo...
