摘要
采矿爆破中经常使用炮泥等材料进行堵孔,堵孔可以增强爆破效果,作用十分重要。通过数值模拟的手段比较无堵孔、炮泥堵孔和炸药堵孔三种状态下的爆破效果。分析结果表明,炮泥堵孔具有用药量小、爆破效果好的优点。
Tamping plug is frequently used as stemming in the mining blasting,which can improve the blasting effect.It is very important in blasting operation.Three conditions,such as no stemming,with tamping plug stemming and with explosive stemming,are numerical simulated in this paper to contrast the blasting effect.The result show that tamping plug stemming can use less explosive to obtain good effect.
