| Abstract: | This paper discusses the aim and significance of control of over-excavation, then, analyses maim factors that affect over-excavation of tunnel. By experiment in-situ, the new methods of control of over-excavation are explored. The results of experiment indicate: most effective methods are selection of reasonable blasting parameters, decoupling of charge, interval charge of small diameter No. 1 explosive of smOoth blasting or bunch of detonating cord, millisecond electronic eaual-difference detonator. |
