摘　　要：在双层多硐室爆破中,采用多集团药包不均衡组合作用、多点微差起爆技术,一次性拦腰强松动爆破构筑了山体平台;降低了施工难度,确保了工程进度和施工安全。本文阐述了该工程爆破方案及参数的特点,所总结的成功经验与体会很有借鉴意义。In a double layer multi-chamber blasting engineering,multi-group charges with unbalanced combination function and multi-point millisecond igniting technique were adopted in loose blasting the mountain body platform at its waist section in one step. The blasting difficulty was reduced, and working schedule as well as the construction safety was ensured. The present paper was a summary of this blasting construction in terms of the introduction of the blasting program and its parameters employed. The successful experience and knowledge set a good example for similar project in future.
