摘要(Abstract):

提出了岩石爆破破碎过程的分形理论,并将其应用于确定微差爆破起爆时间,从而建立了微差延期时间优化的新思路、新方法。本文以平巷含空孔直眼掏槽微差起爆时间为例进行分析和论证。
The fractal theory on rock breaking by blasting is established in this paper That is applied to determine the delay time of millisecond blasting This is a new way by which the optimum delay time of millisecond blasting can be chosen The delay time for parallel cuttimg millisecond blasting in adit with empty holes is taken is discussed in this paper

关键词(KeyWords): 直眼掏槽,微差爆破,延期时间
