摘　　要：本次平巷贯通井筒工程采用松动爆破法,贯通前采用爆破漏斗实验确定贯通地段的最小抵抗线和炸药单耗等基本参数。松动爆破施工时采用合理的降震措施,本次贯通达到了较好的效果,可以对以后的施工起到指导作用。The loose blasting method is adopted in the tunnel perforating shaft engineering,and the basic parameters such as the minimum resistance line and the single consumption of the explosive are determined by the blasting funnel experiment before the penetration.Reasonable blasting measures are adopted in loose blasting construction.This connection has achieved good results,which can play a guiding role in the future construction.

关 键 词：爆破漏斗实验 降震措施
