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 geologicaI factors that control coal-and-gas outburst of Zhaogezhuang Mine are in-situ stresses and coal structure.
