断底卸压在防治冲击地压中的应用

Application of Floor Breaking and Pressure Relief in Prevention and Control of Rockburst

根据古城煤矿32采区特殊的地质条件,对深部条件下的底板冲击地压发生机理进行分析,提出采掘期间冲击地压综合治理方案并加以实施,特别是应用了底板爆破卸压技术,为大采深条件下采掘底板型冲击地压治理工作提供新的综合治理思路。

According to the special geological conditions of No.32 mining area in Gucheng Coal Mine,this paper analyzed the mechanism of floor rock burst under deep conditions,put forward and implement the comprehensive control plan of floor rock burst during mining,especially applied the technology of floor blasting and pressure relief,which provides a new comprehensive control idea for the control of floor rock burst under the condition of large mining depth.
