摘要
从深孔爆破工艺出发 ,分析了提高延米爆破量的主要途径 ;利用隔孔孔间微差爆破技术 ,增大炮孔的密集系数和增加一个自由面 ,达到爆破矿岩块度比较均匀 ,爆堆合理 。
Based on deep hole blasting technology,the main ways of raising blast quatity per metre of hole are analyzed.It has been achieved good effects such as well distributed blasting ore lump,reasonable blasting heap,lower earthquake and blast wave through using partition hole small opening short delay blasting technology,adding close coefficients of blast hole and increasing a free surface.
