In order to study the process and mechanism of coal and gas outbursts caused by dynamic loads in complex stress environment of deep mining condition, coal and gas outbursts simulation equipment under static and dynamic loads is developed based on the similar outbursts simulation devices proposed before. The test device is composed of a coal sample room, an outlet unit, a loading system and a measuring system used to investigate the properties of gas adsorption and desorption, seepage characteristics under the condition of static and dynamic loads. This experimental facility can be used to simulate the phenomenon of coal and gas outburst under the coupling action of static and dynamic loads. The results show that there is more liability of coal and gas outburst induced by non-gas desorption and non-coal pillar than that by gas desorption and coal pillar under a same impact load. And the outburst strength of non-coal pillar is bigger than that of coal pillar. According to the characteristics of the facility, a new formula of evaluating the outburst strength is proposed finally, which may provide a new way to estimate the energy range of coal and gas outburst in the future.
