The utility model provides a simulate secret coal exploitation overlying strata migration and routed sand experimental apparatus of gushing water, belongs to coal exploitation technical field. This experimental apparatus coats the real time monitoring's of the water-bearing stratum water pressure and the water yield similar material simulation experiment in the time of can obtaining under the water-bearing stratum coal seam exploitation. The valve that turns on the water of the pressure water pitcher in the one end of water injection high-pressure rubber pipe and the surface water pressure simulation experiment device is connected, and the other end and the water supply connector on the moulding-die type frame of ore deposit of water injection high-pressure rubber pipe are connected, one end and the surface water pressure simulation experiment device of gas injection high-pressure rubber pipe in the pressure connection of pressure water pitcher be connected the other end of gas injection high-pressure rubber pipe and the articulate of giving vent to anger of gas holder. The utility model discloses can extensively be used for coating under the water or on the pressure-bearing water coal seam exploitation overlying strata migration and gushing water burst among the sand simulation modeling experiment.
