【 摘 要 】

In order to strengthen the prediction of rockburst and inquire the relationship between the rockburst proneness of rock and its surface fractal characteristic, the surface fractal of the rock was studied by fractal method and uniaxial compression test. The change rules of surface fractal of different types of rock were compared by calculating its fractal dimension of rock before experiment and after experiment. Based on the prediction results, we found that the dimension after test is bigger than before test for four kinds of rocks. The rock with stronger rockburst proneness has more intense failure in the loading process and its crack morphology is more complex.
