THE LAYER-CRACK-PLATE MODEL AND TESTING STUDY OF THE ROCKBURST IN MINES
冲击矿压的层裂板模型及实验研究

The rockburst in mines is local instability during excavation, which is related to layer crack plate construction. The formation and buckling of layer crack plate construction are analyzed. The stress criterion of crack growth and the construction buckling instability condition are given. The results of experiment based on this idea coincide basically with theory analysis.
