| 摘 要： | 堆石坝要求石料供量大、粒径级配好,常规中深孔爆破不能满足石料供量要求;硐室爆破大块率高,不能满足粒径级配要求.为此在泽雅水库采石场采用了以条形药包硐室爆破为主,中深孔爆破补充的微差组合爆破石料开采方案.实际爆破表明,供量和粒径级配基本满足工程要求.

| Abstract: | The rock-fill dam requires a large amount of supplied stones with suitable grades.Medium-deep hole blasting can not satisfy the requirements of stone amounts,and chamber blasting can not satisfy the requirements of stone grades because boulder yield is high.As a result,the millisecond combination blasting with chamber blasting mainly and medium-deep hole blasting supplemented was adopted in stone exploitation of the Zeya reservoir.The practice indicates that amount and grades conform to the requirements of the project. |
