The utility model discloses a power system for a coal and gas outburst power effect simulation experiment, which comprises a pressure container for being filled with simulation experiment material, and the pressure container is fixed on the ground and is provided with a container opening; a container inflation hole and a coal inlet capable of being opened and closed are formed in the pressure container. The power system further comprises an outlet device connected to the container opening and an experiment roadway, an explosion relief mechanism used for sealing the container opening and opening the container opening under exerted pressure is arranged in the outlet device; coal particles are added into the pressure container from the coal inlet, poisonous gas is inflated from the container inflation hole; when the pressure reaches the blast point of the explosion relief mechanism, the container opening is instantly opened, at this moment, the pressure container is communicated with the experiment roadway, the coal is broken and thrown away, and the power effect simulation experiment is begun. The power system for the coal and gas outburst power effect simulation experiment is simple in structure, and facilitates more clearly knowing the generation and development law of the outburst hazard generation mechanism of the coal and the gas, as a result, the outburst hazards of the coal and the gas are effectively controlled.
