Abstract：In recent years, our coal mine safety production situation is still serious, the coal and gas outburst is a powerful natural disasters in the production of coal mine.It is a serious threat to the safety of coal produc-tion.As the coal mining depth and strength increases, the coal and gas outburst is becoming more and more serious.So in order to study the influence factors of gas outburst, industrial analysis experiment, elemental analysis experiment, coal and rock experiment, scanning electron microscopy experiment and mercury injec-tion experiments and gas irradiation experiment were conducted, then a conclusion from the analysis of the coupling factors using each index parameter to contrast with the initial velocity of gas radiation was drawn.
