Simulation system used for simulating coal mining and simulation test method

The present invention discloses a simulation system used for simulating coal mining. The system comprises a test box, a similar coal seam bottom plate similar to a bottom plate of a to-be-simulated and mined coal seam is poured at the bottom of the test box, and at least two similar coal pillars similar to the coal pillars of the to-be-simulated and mined coal seam are poured on the similar coal seam bottom plate at intervals. A simulation coal seam is arranged between the adjacent two similar coal pillars and is formed by arranging a plurality of drawable simulation mining tubes, and at least one similar rock mass layer similar to the upper rock mass layer of the to-be-simulated and mined coal seam is poured above the simulation mining tubes. The present invention also discloses a simulation test method. The simulation system and the simulation test method provided by the present invention can simulate the coal seam mining process, and have the important meaning for researching a roof and floor rock mass damage and fracture development process and a disturbance rock stratum seepage characteristic change and evolution rule on a water protection mining condition and during the coal seam mining process.
