基于响应面法的矿岩爆破效果影响因素分析
Influence factors for the blasting effect of ore-bearing rock based on response surface method
摘要
Abstract
In order to analyze the influence factors for the blasting effect of ore-bearing rock, some Box-Behnken design (BBD) experiments were performed, and the effect of bottom burden, drilling spacing and filling length on the blasting boulder, fines ratio and blast quantity per meter of hole was investigated. The response surface regression models for measuring the effect rule of blasting parameter content on blasting effect were established. The results show that the blasting effect is not only largely influenced by bottom burden, spacing in drilling and filling length, but also affected by the interacted affection of the three factors. In a certain range, with the growth of bottom burden, spacing in drilling and filling length, the variation trend of boulder yield and fines ratio is firstly decreasing and then increasing, but the variation trend of blast quantity per meter of hole is firstly increasing and then decreasing.关键词
