摘要
针对淄博矿业集团葛亭煤矿16#煤层含有硫化铁硬夹矸的实际情况,在分析深孔预裂爆破的基本原理的基础上,提出了深孔预裂爆破的材料和工艺,并且介绍了爆破的炮眼间距、炮眼深度、装药量等基本参数。
Aiming at the situation that 16# coal seam contains iron sulfide hard band in Geting coal mine of Zibo Mining Group Co.,Ltd,based on the analysis of deep-hole pre-splitting theory,the paper proposed the materials and processes of deep-hole pre-splitting blasting and introduced the parameters of borehole spacing,borehole depth,charge amount.
