摘　　要：　本文对露天多段深孔微差爆破孔网参数进行了优化,使每排炮孔成直线排列,两排之间成交替正三角形排列,优化设计后,爆破作用比较均匀,大块率下降了56%,同时,爆破根底产生的机会和程度也大大下降。The pattern parameters of deephole bench-millisecond blasting in open pit are optimized, the holes are arranged in a line cach row, and in a triangle between rows. As a result, the function of blasting is improved evenly and boulder yield is greatly reduced, as well as the opportunity producing blasting root is remarkabl remarkably, lowered.
