Experimental device convenient for engagement in coal mining simulation and use method thereof

The invention relates to an experimental device convenient for engagement in coal mining simulation and a use method thereof. The experimental device includes a vibration table, H-section steel, an application device, a connection device, a critical steel bar assembly and a limit assembly. The upper surface of an upper top plate of the vibration table is fixedly mounted with the H-section steel. The upper surface of the upper flange of the H-section steel is provided with the application device, and the application device is specifically a jack. The experimental device is firmly fixed by adding steel plates and using extended bolts, so the relative displacement between concrete frame columns and a device for applying coal mining action is avoided, thereby realizing the firm combination between the device for applying coal mining action and a base H- section steel. The fixed end constraint in the real working condition is simulated, and then different working conditions of the buildingsettlement during the coa
