网络雷管逐孔起爆技术在昆钢龙山石灰石矿爆破中的降震作用

Role of Network Detonator's Hole-by-hole Blasting Technology in Blast-induced Vibration Reduction

针对中深孔排间微差爆破次生震动拉裂矿区周围民房墙体的危害进行分析对比,重点讨论孔间微差网络雷管逐孔起爆技术在昆钢龙山石灰石矿爆破中的推广应用。应用结果表明,该技术解决了昆钢龙山石灰石矿的爆破降震问题,有效降低了爆破次生震动对矿区相邻的石甸口村民房的危害。

Damages from inter-row in deep-hole blasting vibration of secondary fracturing to the surround- ing house walls were analyzed. Application of the detonating technology of hole-by-hole detonators in Kunming Steel Lungshan limestone Mine was discussed. The technology solved the problem of blast re- duction, effectively lower the danger to the surrounding houses.
