Abstract This paper gives an overview of achievements in forecasting rock impact and earthquakes based on the concentration criterion and the evolution law of temporal parameters of dynamic events in fracture processes in the last 30 years. At first，the physico-mechanical meaning of concentration criterion is clarified. Then，the self-similarity of deformation and fracture of rock mass at different structural hierarchies and the fractal natures of the concentration parameters of fracture are introduced. At last，the approaches of forecasting of rock impacts，micro-seismicity in mining regions and earthquakes with different energies and the efficiency of these approaches are overviewed. It is believed that the overview will be helpful for the scholars in this area in China.
