Abstract: A horizontal jet-mechanical combined rock breaking test device and method. The device includes a horizontal base. One end of the horizontal base is provided with a multi-mode cutter head. A jet-mechanical combined cutter is provided on the multi-mode cutter head. The other end of the horizontal base is provided with a surrounding rock stress simulation bin for loading a rock sample. The multi-mode cutter head is connected to a driving mechanism, and the multi-mode cutter head is configured to advance and rotate horizontally along the horizontal base under the action of the driving mechanism, so that the jet-mechanical combined cutter is capable of acting on the rock sample.

Abstract: A pressure three-dimensional non-uniform loading/unloading and steady pressure model test system has a pressure three-dimensional non-uniform loading/unloading device. The pressure three-dimensional non-uniform loading/unloading device is controlled via an input instruction of the hydraulic loading/unloading and steady pressure automatic control system to carry out pressure three-dimensional gradient non-uniform loading/unloading and steady pressure control. An automatic model displacement test system automatically acquires the displacement of any part inside a test model. A multi-probe peeping system observes a cavern excavation deformation and failure process dynamically in real time.
