The utility model discloses a coal sample warming simulation test bench. The coal sample warming simulation test bench comprises an air generator, a temperature control cabinet, a temperature control device for heating control on the interior of the temperature control cabinet, and a gas detector, wherein a coal sample placing platform is arranged inside the temperature control cabinet, an air inlet is formed in the bottom of the temperature control cabinet and communicated with the air generator through an air guide pipe, an air outlet is formed in the top of the temperature control cabinet and communicated with the gas detector through an air guide pipe, and a pressure relief device is installed at the air outlet of the temperature control cabinet. The coal sample warming simulation test bench provided by the utility model is small in size, less in needed coal quantity and strong in experiment maneuverability, and can be used for truly simulating warming and oxidizing processes of underground coal and detecting index gas in the warming and oxidizing processes of coal samples so as to have a good prevention effect on coal spontaneous combustion in a process of production in coal mines.
