兴安煤矿深孔爆破技术防治冲击地压应用

Application of deep hole blasting technology to prevent and control rock burst in Xing'an Coal Mine

深孔爆破技术防治冲击地压是以动静载诱发冲击理论为基础,动载扰动在冲击地压发生中起到重要作用。实践表明,采用装药器提高了施工效率,在煤矿深孔爆破中发挥了重要作用,使深孔爆破预裂坚硬顶板效果更好,有效防治了冲击地压。

Deep hole blasting technology is based on the theory of dynamic and static load induced impact, and dynamic load disturbance plays an important role in the occurrence of rock burst. The practice showed that the use of the charging device improves the construction efficiency and plays an important role in the deep hole blasting in coal mine, making the deep hole blasting presplitting the hard roof better and effectively preventing the rock burst.
