Mining coal face support simulation experiment device

The invention relates to the technical field of coal mining simulation experiment equipment, in particular to a mining coal face support simulation experiment device, which comprises an experiment box, the experiment box is made of a transparent glass material, a plurality of support plates are supported at the bottom in the experiment box through a plurality of hydraulic cylinders, and a rock collapse simulation mechanism is arranged above the support plates. The rock mass collapse simulation mechanism is used for simulating the pressure of a fracture collapse part on the supporting plate when the rock mass above the working surface of the coal mining roadway is fractured and collapsed, so that the supporting strength of the supporting plate in the coal mining roadway is adjusted; the discharging quantity control assembly is used for discharging rock blocks above the supporting plate in a quantity control manner, so that the rock mass collapse simulation mechanism can conveniently perform a pressure simulati
