dear sir
maximum blast size shall depend upon the following factors for optimisation.
1. width of the bench
2. burden and spacing
3. capacity of dumpers provided with this shovel
4. expected output from each shift
5. permission for sleeping hole from dgms to carrry out large blast
6. availability of structures not belonging to owner to minimise blast vibration
7. availability of sms pump truck and sufficient explosive for down the hole loading of explosives
8. optimal blast size shall be 2 to 3 days output from this shovel to minimise frequent marching of the machine to reduce machine idle time
hope u will find this information useful
