摘要/Abstract

摘要： 紫金山金铜矿露采边坡具有落差高、坡角陡、风化程度高等特点，在爆破过程中维持边坡的稳定是矿山开采过程中需要重点关注的内容。在金铜矿露采最终边坡爆破作业过程中，对预裂爆破参数和影响因素开展了系统的分析研究，确定出相关的参数，最终实施结果显示，爆破达到预期效果。研究成果对相同类型的矿山边坡设计具有较好的参考意义。

Abstract: The open-pit slopes in Zijinshan Gold-Copper Mine have the characteristics of various heights, steep slope angles, and high degrees of weathering. Maintaining the stability of these slopes during the blasting is one of the aspects in mining operation that needs to pay special attention. In order to reach the optimum effect of the pre-split-ballasting, the blasting parameters and their affecting factors are systematically studied in this paper. The blasting results are satisfactory.
