摘　　要：介绍了利用药包群的多点微差起爆，采用硐室爆破开挖沟槽的方法，这对如何利用药包群的合理布置、装药量和起爆顺序及时差来提高硐室爆破的抛掷率、改善破碎效果及减少爆破危害具有指导作用。The method of excavating channel by using of initiating chamber of charges 0f multiple pointmicro- delay initiation was introduced in this paper. It' ll have guidance effect for increasing therate of throwing,fragmentation rate of chamber blasting and reducing blasting nuisance by usingof sensible arrangment of charges,charging weights,initiating sequence and time-delay.
