井下中深孔爆破设计参数的优化

Optimization of Underground Medium-length Hole Blasting Design Parameters

介绍了由于采用原有中深孔爆破参数爆破后大块率较大等原因,影响了出矿效率。因此,对部分中深孔设计技术参数进行了分析研究,确定合理选用爆破参数。

This paper presents that due to higher bolder yield caused by existing medium-length hole blasting, the ore drawing efficiency is affected. Therefore partial medium-length hold design parameters were analyzed and studied to determine the reasonable blasting parameters.
