The invention discloses a method for simulating roadway rock burst based on coaction of a static load and a blast load. The method comprises the following steps of: A, selecting cement mortar and ramming a model in a rock model testing machine, and embedding a pressure sensor, an acceleration sensor and a strain gage in the model body; B, maintaining the model body within 28 days, applying initial crustal stress to the model body by utilizing the rock model testing machine, and testing force and deformation field distribution characteristics of the model body under the action of the static load; C, simulating actual cavern excavation characteristics, and measuring force and deformation field distribution characteristics in the model body after excavation each time; and D, drilling in the model body, mounting explosive cartridges and detonators in the drill bores, filling with loess, and detonating the explosive. By utilizing the method, the occurrence scale and time of deep roadway rock burst can be effectively predicted, damage of rock burst disasters on mine production settings can be reduced, the mine safety production risk is greatly reduced, and the production efficiency of the mine is greatly improved.
