摘要
岩体中主结构面是控制岩体爆破效果的主要因素之一。在地下矿山深孔爆破中,合理运用主结构面控制爆破技术,可以提高每米崩矿量、降低炸药单耗、减少二次破碎量,极大地改善矿岩的爆破效果。
The rock mass main structure is one of the main factors that controls the rock mass blasting effect.In deep hole blasting of underground mine,rationally using the control blasting technology of the main structure face may increase rock yield per meter and decrease explosive consumption.It also may reduce secondary crushing amount and greatly improve the ore rock blasting effect.
