Experimental equipment for simulating impact-type rock explosion

Abstract

The invention provides experimental equipment for simulating impact-type rock explosion. The experimental equipment comprises a rack and a specimen box assembly as well as an X-axis-direction loading mechanism, a Y-axis-direction loading mechanism, a Z-axis-direction loading mechanism and a control system which are installed on the rack. The loading mechanism in the first direction comprises four support pillars, a first frame, a second frame, a loading hydraulic cylinder and a screw rod, wherein the four support pillars are arranged in a rectangular shape; the first and second frames are aligned to each other and are respectively fixed at two ends of the four support pillars; and the loading hydraulic cylinder and the screw rod are arranged on the two frames respectively. The experimental equipment is capable of loading static stress and disturbing load on a rock specimen in the three mutually vertical directions in a three-dimensional space, so that the experimental equipment can be used for an experiment for simulating the impact-type rock explosion. In addition, as the structures of the three loading mechanisms are almost same and have good symmetry, the operation of loading stress or disturbing load on the rock specimen in the three directions is easier to control, and the accurate control on the operation is easy to achieve.

Description

technical field [0001] The invention relates to the field of deep mine engineering rock mass mechanics and geotechnical engineering research, in particular to a simulated impact rockburst experimental equipment. Background technique [0002] With the development of geotechnical engineering such as mines, water conservancy and hydropower, and railway (highway) traffic tunnels, rockburst, as a very dangerous disaster phenomenon in deep mines, occurs more and more frequently. Rockbursts are sudden and violent, and the rock fragments ejected during the destruction carry a large amount of energy, which will pose a threat to equipment and personnel, and even endanger life in severe cases. [0003] As we all know, blasting is an indispensable construction method for large-scale water conservancy, tunnel, mining engineering, and nuclear power engineering rock mass excavation. When the explosive explodes in the rock mass, it releases a large amount of explosive energy instantaneousl...

Problems solved by technology

At present, most of the experimental equipment used for rock sample experiments are not rigid enough, and the vertical loading of the force in the X direction, Y direction, and Z direction cannot be accurately guaranteed during the experiment process, so it is difficult to induce the rockburst phenomenon and affect the rockburst mechanism. analysis, research
