Summary: | The invention discloses a three-dimensional test device and method for simulating overlying strata motion characteristics under mining influence. The device comprises a loading device, a test box and an overlying strata motion monitoring device, the loading device comprises a press machine supporting frame, a hydraulic oil cylinder, an oil pressure controller and a test box pressing plate; the test box comprises a box body and a coal and rock stratum simulation device. The coal rock stratum simulation device comprises a chassis, a vertical lifting rod, a small flat plate, a hinge ball, a hinge controller and a small hydraulic controller; the overlying strata motion monitoring device comprises a stress sensor, an acoustic emission sensor, a thermal infrared imager, a 3D laser scanner, a miniature high-definition camera and a data acquisition processor. The device is simple in structure and convenient to use, various mining methods can be simulated, mining parameters can be freely adjusted, the fracture form an |
