摘要
福建紫金山金矿计划2008年露采采剥总量1400万m^3。随着穿孔爆破作业的不断推进,有些地段已经接近或达到最终开采边界。通过精心设计和选取预裂孔、缓冲孔、主爆孔的爆破参数、装药结构及起爆网路,使预裂爆破达到了稳定最终边坡的效果,为探索适合该矿的预裂爆破参数,做了有意义的尝试。
The total stripping quantity of Zijinshan Gold Mine, Fujian, China, comes to 14 million cube meter in 2008. With the continuous advancement of drilling blasting, some mining sections are approaching or reach its final mining boundary. The paper discusses a presplitting blasting responsible for a blasting effect of stabilization of the slope in terms of its careful design and determination of the parameters of presplitting hole, cushion hole, primary blasting hole as well as the charge structure and initiating circuit. The paper makes a significant attempt to a rational presplitting blasting for the Mine.
