摘要
露天矿山生产爆破的矿岩块度是矿山生产的重要指标,对矿山生产有重要影响.为了对矿山生产爆破的矿岩块度进行精准预判,统计岩体质量、炮孔间距、炮孔排距和炸药单耗等矿岩爆破块度影响指标,构建了包括以上指标因素的响应曲面试验方案.根据试验结果对矿岩爆破块度指标因素进行了单因子和多因子交互作用分析.采用Design-Expert软件对矿岩爆破块度目标值进行了求解,以此寻求炸药单耗最小的爆破结构参数.实例证明:响应曲面法可以对露天矿山矿岩爆破块度进行深入全面的分析,其对矿岩爆破块度的目标求解方案也可以用来对爆破参数进行优化,得到炸药单耗最小、最为经济的爆破参数方案.
Abstract
The rock fragmentation of open-pit mine production blasting is an important indicator of mine production and has a significant impact on mine production.In order to accurately predict the rock fragmentation of mining production blasting,the impact indicators of rock mass quality,borehole spacing,borehole spacing,and explosive consumption on rock fragmentation were statistically analyzed.A response surface test plan was constructed,including the above indicators.Based on the experimental results,single factor and multi factor interaction analysis were conducted on the fragmentation index factors of ore rock blasting.The Design Expert software was used to solve the target value of rock fragmentation in mining blasting,in order to seek the blasting structural parameters with the minimum explosive consumption per unit.Example proof:The response surface method can conduct in-depth and comprehensive analysis of the fragmentation of open-pit mine rock blasting,and its target solution scheme for rock blasting fragmentation can also be used to optimize blasting parameters,obtaining the blasting parameter scheme with the lowest explosive consumption and the most economical.
