· The system is very flexible and many explosive and initiating systems can be used as mentioned previously. For snakeholing, about 1 lb of explosive per cubic foot of rock opposite the charge is needed. When boulder blasting in crushers, less explosive should be used in that the boulder only needs to be cracked or jarred.
