摘　　要：深孔爆破松动是目前预裂隐蔽构造常用技术,但是其爆破机理还有待深入研究。文章探讨了深孔爆破的优势和机理,结合山西余吾煤业S5101工作面过DX6陷落柱的爆破实践建立深孔爆破模型,分析爆破半径和效果得出结论:深孔爆破预裂隐蔽构造采用深孔爆破的方法可降低岩石强度,控制生产成本,确保生产安全,提高生产效率。Deep hole blasting loosening is the current pre-cracking hidden structure commonly used technology,but its blasting mechanism is still to be in-depth.This paper discusses the advantages and the mechanism of deep hole blasting,combined with the Shanxi Yuwu Mine S5101 face over DX6 trap column blasting practice to establish a deep hole blasting model,analysis of the blasting radius and effect of the conclusion:deep hole blasting pre-cracking of hidden structures using the method of deep hole blasting can reduce the strength of the rock,control the cost of production,to ensure the safety of production,and improve the efficiency of production.
