摘　　要：On basis of an analysis of the geological condition, law of gas outburst and materials about coal-and-gas outburst, this paper summarized the characteristics associated with coal-and-gas outburst of Zhaogezhuang Mine and studied the factors controlling coal-and-gas outburst such as stress, coal structure and gas pressure, content of gas. Then, based on a comparison of effects of in-situ stresses, coal structure and gas on coal-and-gas outburst of Zhaogezhuang Mine, the paper concludes that the major geological factors that control coal-and-gas outburst of Zhaogezhuang Mine are in-situ stresses and coal structure.
