| Abstract: | By adopting the technique of blasting control such as millisecond delaysconstricted blasting, that is,to select the right blasting parameters for fracturestructure ore bodies, suitable initiation mode and delay periods. The ratio of coarsefragmentation is reduced from 30% to 10% .The methods and experiments are statedin this paper. |
