摘要: 贵州六盘水红桥新区工业园区是典型的喀斯特溶岩地质地貌,岩层积水、溶洞多且存在很多裂缝,在前期的工程爆破中经常出现局部盲炮现象。结合工程实践所出现盲炮的原因进行分析和总结,同时提出了预防措施。按照所提出的预防措施进行爆破作业,爆后盲炮率明显降低,可见这些措施是切实可行的。

Abstract: Industrial park in Hongqiao New Area of Guizhou Liupanshui is typical karst geological features.And there is a lot of rock seepage water,caves and cracks in rock.As a result,blind shots phenomenon often appears in local places in early engineering blasting.This paper analyzes and summarizes the causes of the blind shots combining with the engineering practice,and some preventive measures are put forwards.Then,the explosion blind shot rate is reduced significantly after explosion operations according to the prevention measures.It is thus clear that these measures are feasible.
