Abstract

The invention discloses a three-dimensional similar simulation system capable of simulating a false roof. The three-dimensional similar simulation system includes a three-dimensional similar simulation experiment platform (1); a coal seam simulation system, a false roof simulation system (4) and other rock layers are arranged in the three-dimensional similar simulation experiment platform; the coal seam simulation system comprises a plurality of jacks arranged in order from left to right; each jack includes a movable column (2) and a jack cylinder (3) connected to a rear end of the movable column; the false roof simulation system (4) is disposed the upper portions of the movable columns (2) and includes a plurality of false roof simulation sheets arranged in order from front to back; eachfalse roof simulation sheet is composed of a plurality of iron sheets (5) hinged from left to right in order. The three-dimensional similar simulation system capable of simulating the false roof can completely restore and simulate a coal seam mining scene and research on the influence law on top and bottom plates, and can restore the coal seam mining site state to the greatest extent.

Description

technical field [0001] The invention relates to teaching research and scientific research experiments in the field of mining, in particular to a three-dimensional similar simulation system for simulating false roofs. Background technique [0002] The three-dimensional similar simulation is the optimization and improvement of the traditional similar simulation experiment. The traditional two-dimensional similar simulation width is only 20cm, and the influence of the boundary effect on the production pressure is not considered at all. At the same time, the similar simulation has not considered the influence of the false roof so far. These are not fully consistent with the principles of similar experiments. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-dimensional similar simulation system capable of simulating false roofs. The system completely restores the simulated coal seam mining scene and studies the...
