Abstract Based on self-developed large-scale simulation test system of coal and gas outburst，experimental verification of its reliability is carried out；and experimental study of simulation of variation laws of intensity of coal and gas outburst is done under different water contents of coal as well. It is shown that：(1) the simulation results obtained by the large scale simulation test system of coal and gas outburst are fairly consistent with actual results of coal and gas outburst；(2) the reliability is satisfactory；(3) both possibility and intensity of coal and gas outburst decrease with the increase of water contents of coal；and (4) under the test conditions，the relationship between the water contents and intensity of coal and gas outburst is conic.
