| Abstract: | Small burden deep hole millisecond blasting technique for the reduction of oversized blocks in artificial aggregate preparation in Geheyan Hydraulic Project (Hubei Prov., PRC) is advanced theoretically. Through four full-scale-in-situs experiments, applicable drilling and blasting parameters and suitable millisecond detonation method are found out. Appropriate technical measures are proposed correspondingly. |
