摘要
总结了王甫洲水利枢纽赵岗块石料场爆破试验成果 ,提出了合适的钻孔爆破参数、合理的装药结构、微差起爆方式及间隔时间 ,推导了爆破岩石块度分布Russian Rammler方程 ,给出了提高开采获得率的一些建议。
The achievements of experimental blasting in Zhaogangkuai quarry for Wangpuzhou key water control project are summarized. The suitable drilling blasting parameters, reasonable charging stucture, millisecond firing and interval time are put forward. The Russian-Rammler formula for predecting fragments distribution of blasted rocks is deduced, and some proposals of improving the mining output are given.
