The invention relates to a dimension and dip angle adjustable type coal mine stope similar model test system and method. The system comprises a model bearing frame, a pressure loading device, a model frame rotating device, a centralized control device and a monitoring device, wherein the model bearing frame is used for laying a stope similar model; the centralized control device is used for sending a pressure application control instruction to the pressure loading device according to a pressure value set by the test and sending a rotation control instruction to the model frame rotating device according to a dip angle value set by the test; the pressure loading device is used for applying pressure to the model bearing frame according to the pressure application control instruction; the model frame rotating device is used for enabling the model bearing frame to rotate by the set dip angle according to the rotation control instruction; the monitoring device is used for monitoring the state of the stope similar model in an excavation process. With the adoption of the system provided by the invention, the pressure characteristics of a coal working face of different dip angles, different buried depths and different coal seam thicknesses of a coal mine site can be simulated in a laboratory.
