| 摘 要： | 地下矿山大直径深孔分层装药爆破时，每个炮孔要分段多次利用。固体封孔的装药结构频繁发生炮孔堵塞，水封孔爆破可有效地解决这一问题，但水封孔可能引起装药结构产生位移或泄漏本文列举了一些解决对策。

| Abstract: | In crater retreat blasting at underground mines,each largediameter hole will be used time and again.The hole remained may be blocked up frequently after blasting if the solid granular material was used for stemming.The application of water infusion blasting is effective to solve the problem.But water infusion may cause the charging structure displacing or escaping.Some countermeasures are presented in this paper. |
