Abstract

The invention discloses a mining similar simulation experimental frame realizing adjustable stratum dip angle and multi-directional loading. The simulation experimental frame comprises an experimentalmaterial mounting frame, a counterforce frame and a jack, wherein the counterforce frame is mounted on the periphery of the experimental material mounting frame, and the jack is mounted on the counterforce frame to act on the experimental material mounting frame. According to the mining similar simulation experimental frame realizing adjustable stratum dip angle and multi-directional loading, with the technical scheme of the first combination of multi-directional stress and variable dip angles, moving variation of overlying rock strata in different stress states at each angle of coal seams can be simulated, experiments can be completed only by changing parameters for the coal seams under different geological conditions, movement deformation characteristics of the overlying rock strata indifferent stress environments at any angle after coal seam mining can be obtained, and experiments in various complex environments can be conducted according to working conditions, so that the simulation experimental frame is of great significance for guiding actual production.

Description

technical field [0001] The invention relates to the technical field of mining engineering, and more specifically relates to a similar simulation experiment rack with adjustable inclination angle and multi-directional loading for mining. Background technique [0002] At present, similar simulation experiments are still a common method for studying mining engineering problems. The similar simulation experiment frames on the market can be divided into plane model frames and ordinary three-dimensional experiment frames. Coal mining face with large inclination angle and complex stress. As the mining depth and intensity of underground coal mines continue to increase, the underground engineering environment becomes more and more complex, and the requirements for similar simulation experiment devices also increase accordingly. Compared with the plane model frame, the ordinary three-dimensional similar simulation experiment frame can be more realistic It reflects the movement of roc...
