Embodiment Construction
[0025] Below in conjunction with accompanying drawing, by describing embodiment, the present invention will be further described:
[0026] like figure 1 , 2 As shown, the controllable experimental device for simulating roadway unloading in the present invention includes a similar material simulation system A, a high-pressure impact system B, and a signal acquisition and analysis system D. The high-pressure impact system B is connected to the high-pressure gas control system C through a high-pressure gas delivery pipe 2 .
[0027] like image 3 As shown, the material similarity simulation system A includes a frame-shaped simulation frame 17, and a similar simulation material 9 is arranged inside the simulation frame 17. The similar simulation material 9 has the same lithology as the required surrounding rock, and a hole is left in the center of the similar simulation material 9. There is a filler 13 inside, and the proportion of each material of the filler 13 is consistent w...
