Large three-dimensional dynamic load mineral similar material physical test platform

Abstract

The invention provides a large three-dimensional dynamic load mineral similar material physical test platform. A square structure is encircled by a front baffle, two side baffles, a back baffle, and an upper end face between a top plate and a substrate; a simulative rock layer is filled in the square structure, and a simulative laneway is arranged in the simulative rock layer along the cross direction; one end of the simulative laneway is provided with a simulative coal layer, and the other end is connected to the outer part of the front baffle; a mini sized coal cutter is arranged in the simulative laneway, and a high-speed camera is arranged on the mini sized coal cutter; outsides of the baffle and the top plate are further provided with supporting parts; jacks are distributed at the outsides of the side baffles, the back baffle and the top plate, and the bases of the jacks are fixed on the supporting part. The manufacturing and application of the existed experimental platform are mainly concentrated on the two-dimensional similar material physical simulative test and the three-dimensional static load similar material physical simulative test; a part of dynamic load test platform is hard to carry out for being influenced by the source of the dynamic load, and the experimental study is influenced. The invention belongs to the mineral disaster study field.

Description

technical field [0001] The invention relates to a large-scale three-dimensional dynamic load mine similar material physical test platform device, which belongs to the field of mine disaster research. Background technique [0002] At present, with the development of the mining industry, mine disasters occur frequently and the conditions are more complex and changeable. The research on this issue is also deepening. The traditional theory and experience are slightly insufficient. Due to the complexity and diversity of disasters, Coupled with the limitations of on-site observations, physical simulation experiments have become an important research method, which plays an important auxiliary role in accident reproduction, theoretical analysis and summary. [0003] The production and application of the current similar material physics experiment platform mainly focus on the two-dimensional similar material physical simulation test and the three-dimensional static load similar mater...
