| Abstract: | The paper explains the means of effect testing of working face 2702 by blasting caving coal and the measures of preventing outburst in Yanmazhuang Coal Mine.It consideres that the working face gas pumping and discharging of the outburst coal?seam at caving roof coal is the effective means to prevent outburst.When the working face has outburst,the preventing measures can reduce the danger degree.It has some valuable refference for the similar working face when returning excavation. |
