Abstract
How to ensure the existing tunnel's safety and the train normal running while the electric railway multiple line tunnel was blast boring? By study and practice,the paper gives an answer through stepped digging method, underholing style, holes scatter and the structure of the hole and detonation technology. It receives good technological achievement and remarkable social and economic benefits in practical application. It provides successful experience for the similar engineering in the future too.
