Abstract

The grade evaluation of rockburst tendency is the basis for studying the mechanism of rockburst.Based on the brittle rockburst index(B), Barton rockburst index(α), elastic deformation energy rockburst index(W_et) and impact energy rockburst index(W_cf), the rockburst tendency evaluation index system is established.The rockburst tendency grade evaluation model is established based on the fuzzy matter-element theory.This model is used to evaluate the rockburst tendency grade of typical rocks in Xiaochangba mining area.The results show that both the ore and biotite quartz schist are strong rockburst tendency.As the burial depth increases, the limestone transitions from a weak rockburst tendency to a medium rockburst tendency.The upper plate of the ore body(biotite quartz schist) is a strong rockburst tendency, and the lower plate(grey rock) of the ore body is a medium rockburst tendency.In the actual mining process, the mining project should be arranged in the lower plate as much as possible.The ore body is a strong rockburst tendency, which is consistent with the frequent occurrence of rockburst symptoms in actual mining.It is suggested that the ground pressure monitoring should be strengthened during the mining process and the pressure relief project should be arranged reasonably.
