摘要
在露天爆破过程中,露天挤压爆破技术具有广泛的应用,通过对炮孔的破岩机理进行分析,阐述了挤压爆破的爆破原理,并结合白云鄂博铁矿现阶段应用的抛掷爆破与挤压爆破工程实例对比,优化爆破质量,提高爆破技术经济指标。
In the process of open blasting,the surface tight-face blasting technology is widely applied.In the paper,the principle of tight-face blasting is elaborated through analyzing the rock splitting mechanism of blast hole as well as comparing the engineering practices of pinpoint blasting and tight-face blasting in Baiyunebo Iron Mine at present.Finally,the blasting quality as well as the technical and economical index of blasting are improved.
