Abstract By summing up the results of case analysis and microseismic monitoring，the three periods during rockburst occurred are pointed out. The types of rockburst are newly divided into centralized static load type and centralized dynamic load type，and engineering structure models of two kinds of rockbursts are established；then，energy criteria of rockburst start-up are analyzed，at last，theory of rockburst start-up during coal mining is put forward. The results show that，the intrinsic factor of rockburst stat-up is the excessive accumulation of static load in near-field system of mining rock；the possible areas of rockburst start-up are the maximum peak areas of stress in the region of limit equilibrium；the process of rockburst of two typical cases of rockburst can be analyzed by using the theory of rockburst start-up；and the time series and spatial series of rockburst are corresponded；so a guidance is provided for detection and prevention of rockburst.

Key words： mining engineering theory of burst start-up energy criterion floor burst theory concentrated static load intrinsic factor time series spatial series
