The utility model provides a coal mine goaf temperature distribution law simulation test test device, is including experimental box, experimental box body cover board, hole baffle, entity baffle, load heat source device, temperature monitoring device and air feeder, experimental box is the cuboid form, and the upper end is sealed through experimental box body cover board, has the baffle groove in its long limit face inner wall shaping for fixed hole baffle or entity baffle, the temperature measurement hole has still been opened to experimental box on its long limit face, load heat source device heats through one of them temperature measurement pore pair proof box body cavity body, and the temperature monitoring device is through the internal temperature of all the other temperature measurement hole monitoring proof box body cavitys, experimental box is opened on its minor face face has air inlet and gas outlet, and air feeder is through the air inlet to the internal air feed that carries on of proof box body cavity. The utility model discloses can realize ideal and simulate loose coal body spontaneous combustion in -process heat transfer process to collecting space area heat transfer law is planned simulating in the acquisition.
