露天煤矿中的爆破剥离技术

BLASTING TECHNOLOGY FOR OVERBURDEN STRIPPING IN OPE-PIT COAL MINE

本文介绍在露天煤矿中以抛掷爆破为主 ,预裂爆破为辅进行剥离覆盖物 ,能大幅地降低生产成本 ,提高生产效率。并分析了抛掷爆破 ,预裂爆破的爆破参数。

The paper introduces the technology of casting blast combined with pre\|splitting blast.The technology possesses the advantages of remarkably reducing the production cost and increasing the productivity.The parameters of casting blast and pre\|splitting blast are also described in the paper。
