秦岭硬岩隧道深孔光面爆破专用炸药和工艺的研究

The Special Explosive and Technique for Deep hole Smooth Blasting in Hard Rock of Qinling Tunnel

针对秦岭隧道硬岩深孔爆破的特点研制了新型专用光爆药卷，并在现场试验中结合改进装药工艺，最终取得了较好的光爆效果，降低了装药成本。文中主要介绍了研制和试验过程中的一些体会和感想。

A new special explosive for smooth blasting was investigated and made,which was good for the characteristics of deep blasthole and hard rock in Qinling Tunnel.In addition,the charging technique of perimeter blastholes was improved.Therefor,the excellent smooth blasting were gotten in the test section of Qinling Tunnel,while the cost of charging explosives was cut down.The paper principally introduced some thought and experiences in the investigation and tests.
