The invention discloses a mine coal and gas co-mining composite disaster simulation test system and a mine coal and gas co-mining composite disaster simulation test method, which are characterized in that the geological distribution in a simulated goaf box body is closer to an actual mine goaf by changing the layout mode of each filling area, each extraction roadway and each drill hole in the simulated goaf box body; the gas release gas chamber provided with a plurality of sub-gas chambers is adopted to simulate the gas emission amount of different areas, so that the subsequent ventilation condition, the gas release state and the gas extraction condition are closer to the actual mine goaf; monitoring data of each comprehensive measuring point is obtained in real time through a gas concentration and temperature automatic acquisition system in a test; the computer performs analysis and processing according to the monitoring data to finally obtain the temperature distribution change and gas concentration distrib
