Abstract
An experimental method for simulating an impact rock-burst, comprises the following steps: making a rock sample having a through hole or a half hole; loading initial static stresses of three directions onto the rock sample; then loading dynamic load(s) by 0.5-10 minutes, to determine whether a spalling phenomenon appears on an internal surface of the hole; if appears, and the rock sample is further damaged, determining and recording a failure course, if not appears, increasing the static stress(es) or the intensity of the dynamic load, then repeating the experiment procedure as far as the rock sample goes into the failure course, then determining and recording the failure course, and ending the expierment. The impact rockburst induced by dynamic load is simulated in the rock sample successfully, and by sudying mechanical mechanisms of the rock-burst, the present application lays foundations for gradually understanding and mastering the nature of real rock burst.
