Abstract | The invention discloses a two-dimensional physical similar simulation test bed for roadway mine pressure research and a building method thereof, relates to the technical field of mining engineering, and solves the problems that in an existing similar simulation test, the size of a model cannot be adjusted according to test requirements, and a loading position cannot be well adjusted. Different numbers of vertical force transmission devices and lateral force transmission devices are fixed on the test bed and the movable loading plate, different load strengths are given to a coal rock layer, so that the load bearing state of the model is closer to the condition under the actual geological condition, and when coal and rock layer laying is carried out, the vertical force transmission devices and the lateral force transmission devices are selected according to the size and loading position of the experimental model, the model size and the loading position are adjusted by adopting the force transmission devices of |
