New Rock Burst Prediction Method
This paper gives a new rock burst prediction method of potential index, according to the rock deformation and failure of the rock and the relationship between energy transfer, the characteristics of uniaxial compression stress-strain entire process curve. The new prediction method of rock burst of energy with existing method for forecasting index was compared and analyzed. Testing study was made on the typical rocks of rhyolite, from the deep deposit of Niba mountain tunnel, Combined with the actual phenomen of rock burst, the rock burst potential index is verified to be able to show fairly well the rock burst proneness. Finally, a criterion of rock burst proneness is put forward.
