Summary: | The invention provides a model for researching rock burst of a fracture surrounding rock roadway and a manufacturing method of the model. The manufacturing method comprises the following steps: firstly, manufacturing an impact simulation material by adopting gypsum, a gypsum reinforcing agent and water, and manufacturing a fracture network of a water-soluble material by adopting 3D printing; then the roadway mold is arranged on the model mold in a penetrating mode, and the fracture network is arranged on the periphery of the roadway mold; pouring an impact simulation material into the model mold to fill the fracture network; initial setting of the impact simulation material: the impact simulation material releases heat in the initial setting process, and the released heat and water in the impact simulation material can rapidly dissolve the fracture network into a viscous state, so that the fracture network and the impact simulation material are organically fused; and standing for preset time, removing the mod |
