Abstract
A study of the characteristics of the accumulative rock failure and its evolution by application of the group renormalization method were presented. In addition, the interaction and long-range correlated effects between the immediate neighboring units was studied. The concept of mechanical transference for model OFC, employed in the study of self-organized criticality, and the coefficient α were introduced into the calculation model for group renormalization. With the introduction, mechanisms for the drastic increase and decrease of failure intensity of rocks were investigated under similar macro-conditions.
