STUDY ON MECHANISMS OF ROCKBURST INITIATION AND DEVELOPMENT AND ITS CONSTITUTIVE EQUATIONS
Essentially, microseism is considered as the reflection of energy release in the deterioration process of rock mass, which can be used to monitor and predict the position and time of occurrence of rockburst. However, the uncertainty of the mechanism of rockburst initiation and development restricts the application of microscismic monitoring method on rockburst prediction. In this paper, the mechanism of rockburst initiation and development is revealed by theoretical and experimental studies. The criterion of rockburst occurrence is proposed, which includes the failure criterion of rock mass and the criterion of the limit of energy storage. The constitutive equations of the damage and energy consumption stage and failure stage are established for the process of rockburst initiation and development, based on the least energy consumption principle and brittle plastic theory. Through the use of the microseismic monitoring method, the effective theoretical foundation provides the precise prediction of rockburst.
