Simulation Test on Distribution and Control of Blasting Fragmentation

The rock fragmentation is influenced by some factors as charge structure,blasting parameter and blasting technique besides the properties of rock and explosive.The different blasting parameters are applied to different condition in the practice.The blasting tests are performed by changing blasting parameters such as uncoupling coefficient,specific charge and stemming length on reinforced concrete and nature rock samples,then the sieve and statistical analysis of the rock fragmentation was taken,which optimizing the blasting parameters and controlling and predicting the blasting fragmentation
