摘　　要：隧道一次爆破炮孔分布上百个,依赖工程经验的传统人工绘制爆破方案费事费力。为了研究隧道爆破炮孔智能设计方法,基于公式推导,提出了炮孔平面分布和三维空间分布的数字化方法;再采用计算机编程技术,实现了炮孔参数的程序化,研发了炮孔智能设计系统。研究结果表明:应用隧道轮廓线、掏槽孔、周边孔和辅助孔的参数化表达方法,可以实现隧道炮孔的快速创建,符合隧道爆破需求。通过建立炮孔孔口与孔底坐标的关联关系,可以实现炮孔空间分布的精细表达,直观地指导现场钻孔作业。应用计算机编程方法,可以实现了炮孔布设的智能、精细设计。现场隧道爆后炮孔残痕完整,隧道开挖轮廓成形光滑,整体掘进效果好。研究成果提高了隧道炮孔设计的效率与智能化。There are hundreds of blast holes in a tunnel blasting.Since the traditional manual drawing of the blasting scheme is laborious and depends on the experience of blasting engineering,a digital method for the planar and three-dimensional spatial distribution of blast holes was proposed based on formula derivation to study an intelligent design method for tunnel blasting blast holes.Subsequently,the programming of blast hole parameters was achieved by utilizing computer programming techniques,which can lead to the development of an intelligent blast hole design system.The results show that the parametric expression method of tunnel contour,cut holes,peripheral holes and auxiliary holes can realize their rapid creation and meet the needs of tunnel blasting.By establishing a correlation between the coordinates of the blast hole opening and bottom,a refined expression of the spatial distribution of the blast hole can be realized,and intuitive guidance for on-site drilling operations can be provided.Furthermore,a computer programming method can realize an intelligent and fine design of a blast hole layout.After tunnel blasting,the residual marks of the blast holes are complete,the contour of the tunnel excavation is smooth,and the overall excavation effect is good.The research results can improve the efficiency and intelligence of tunnel blast hole design.
