Abstract: A simulated impact-type rock burst experiment apparatus includes a bracket, a specimen box assembly, an X-direction, Y-direction and Z-direction loading mechanisms mounted on the bracket, and control systems. Each loading mechanism includes four supporting posts in a rectangular arrangement, a first and second frames aligned with each other and fixedly connected to both ends of the four supporting posts, a loading hydraulic cylinder and a lead screw mounted on the two frames respectively.

Abstract: The present disclosure relates to a simulated impact-type rock burst experiment apparatus comprising a bracket, a specimen box assembly, an X-direction, Y-direction and Z-direction loading mechanisms mounted on the bracket, and control systems. Loading mechanism comprises: four supporting posts in a rectangular arrangement, a first and second frames aligned with each other and fixedly connected to both ends of the four supporting posts, a loading hydraulic cylinder and a lead screw mounted on the two frames respectively. The present disclosure is able to load static and dynamic loads to the rock sample in three directions perpendicular with each other, thereby performing experimental method for simulating an impact rockburst. Furthermore, the structures of the three sets of loading mechanisms are substantially the same, which have good symmetry, therefore, it is more easily and accurately to control the operation for loading static or dynamic load to the rock sample.
