摘要：
Focusing on the development process of rockbursts, new development of key aspects is addressed in this paper. First of all, elaborations were made on rockburst types, intensitiesy gradations, typical features induced by the tunnel boring machine(TBM) or the drilling and blasting(D&B) excavation methods, and characteristics in different rock lithology. Then, various technical means for investigating rockburst development process were analyzed, such as the laboratory block scale experiments, physcial model tests, numerical simulation, comprehensive in situ inspection and field monitoring. The development mechanisms of different rockburst types and the microseismcity evolution laws ofin rockbursts development process induced by different excavation methods were thus revealed. Afterward, the rockburst assessmentestimation methods and the quantitative warning methods of rockburst location and intensity based on the in situ microseismicity data were discussed based on the in situ microseismicity data. Moreover, dynamic prevention and controlling techniques were presented for different rockburst types induced by different excavation methods including the optimized excavation design method, optimized stress release design method, optimized energy-absorption support design method and the dynamic control methods. Furthermore, a case study was presented with detail information on rockburst monitoring warning, dynamic control and the applicability of introducing methods. Finally, the future trends on rockburst development process were discussed. © 2019, Science Press. All right reserved.
