摘要(Abstract)：

根据硐室爆破存在冲炮现象，设计了导硐封堵药包。利用封堵药包起爆产生的应力波和爆生气体作用于封堵材料，有效抑制和减少主爆药包爆炸能量的散失和冲炮现象的发生，从而改善爆破效果。本文给出封堵药包的合理位置、起爆时差和药量公式，并列举了工程实例。
The stemming charge in leading chamber is designed to solve the product rushing out of the chamber in chamber blasting When stemming charge is fired,stress waves and explosive air act on stemming materials to control and decrease dissipation of the major energy and to avoid the product rushing out of the chamber,so as to ensure good blasting results in the meantime,the paper provides the rational position,detonating difference and explosive quantity of stemming charge,also Engineering examples are given in this paper
