By blasting test of graded material exploiting for the rockfill dam with face slab at upper reservoir of Zhanghewan Pumped Storage Power Station,this paper amends Kuz-Ram blasting fragmentation prediction empirical model and sets up a blasting fragmentation distributed model of graded material exploiting that fits Zhanghewan Pumped Storage Power Station.

A method for improving graded material mining and a modified method to the Kuz Ram Model based on field test data are proposed.
