The accidents of coal and gas outburst happening from 2013 to 2024 in Guizhou Province have been counted in accordance with the occurrence year, accident grade, accident location and occurrence month in this paper. The average number of the accidents and the dead persons are 1.75 and 14.92 respectively in each year, which can be understand from the statistics. The accidents are only distributed in the relatively major accident and the major accident and happen in Bijie district and the deaths distribute in LiuPanshui district mostly; the least number of the accidents and deaths arise in Guiyang district; the accidents and deaths separate in March mostly and there are no accidents in February and September. In addition, the risk factors of coal and gas outburst are divided into 4 first-level risk factors including personnel, equipment, environment and management and 18 secondary risk factors such as physical and mental quality of workers and so on. It can be concluded by risk assessment flowchart model that the equipment risk factor influences the coal and gas outburst risk system furthest and the personnel risk factor influences secondly and the environment risk factor influences thirdly and the management risk factor influences least. Finally, the associated countermeasures have been proposed in this paper. The above researches can provide the prevention of coal and gas outburst with the reliable and scientific foundation.
