| Abstract: | The experiments of cyclic loading and unloading, uniaxial and triaxial stiffness of rock and the numerical modeling analysis of deep rock mass are completed in Linglong gold mine. Based on the results the experiments and numerical modeling, the phenomena of higher elastic strain energy and the distribution of rather large elastic energy resilience in deep rock mass are analyzed in general. The releasing of the elastic energy resilience has high impact characteristic. The great possibility of rock burst during deep mining excavation in Linglong gold mine are concluded by using various prediction criteria of rock burst. The conclusion is that the rock burst can be forecasted. The methods and the safety precautions against rock burst are also proposed according to the actual construction. |
