摘　　要：针对炮孔存水的特殊工况,基于水压力原理,设计出3种炮孔排水装置,并对其优缺点进行对比分析,选出了最优的设计方案。通过对炮孔排水装置的排水原理及操作步骤进行分析,得出:第3种炮孔排水装置设计和应用较合理,理论上排水率可达100%,从根本上解决了特殊工况条件下存水炮孔的排水问题,扩充了炮孔排水装置的研究理论,提高了爆破效果。According to the special conditions of the blasthole with the water, based on the water pressure principle, three kinds of blasthole drainage device are designed, the optimal design scheme is selected. The drainage device and operation steps are analyzed, then the results show that the third kinds of design and application of drainage device is the most reasonable, theoretical drainage rate can reach 100%, the drainage problem of the blasthole with water is solved in the condition of the special condition. The research theory of the drainage device can be extended and it can improve the blasting effect.
