Summary:The invention discloses a rock mass fracture gas-liquid two-phase seepage experiment device and method, and relates to the technical field of geotechnical engineering, the experiment device comprises:a gas-liquid premixing part, in which a premixing process of carbon dioxide gas and clear water is completed in a gas-liquid mixing box; a seepage part which is used for cementing and fixing the tworock sample plates in a seepage experiment box, wherein a gap between the two rock sample plates simulates a coal body crack and is used as a channel through which gas-liquid mixed fluid flows in a seepage experiment; and a monitoring control part which is used for monitoring and controlling the seepage experiment in real time. The beneficial effects are that carbon dioxide gas is dissolved in clear water in advance under the conditions of high pressure and low temperature, then the temperature and pressure are increased, carbon dioxide is condensed into bubbles in water and is uniformly distributed, and a hardware bas
