逐孔起爆在露天矿生产中的应用研究

Research on hole-by--hole detonation technology applicated In open-pit coal mine

针对某露天矿传统生产中所采用的排间微差爆破效率低、大块率高的问题,提出了逐孔爆破的改良措施。本文对逐孔起爆技术进行了简要介绍,结合该矿生产实践,确定了爆破相关参数,并应用于工程实践,取得了良好的技术及经济效果,为类似生产情况提供了参考。

based on the problem of low efficiency and high bulk rate in the traditional production of an open-pit mine,the improvement measures of perforation blasting are put forward.By hole blasting technique are in this paper,a brief introduction,combined with the mine production practice,to determine the blasting parameters,and applied to the engineering practice,has obtained the good technical and economic effect,provides reference value for similar production situation.
