The carbon and hydrogen combine with oxygen, and the nitrogen is liberated. Dynamite is an explosive consisting of an absorbent substance (for example, sawdust) soaked in nitroglycerin. The absorbent material helps nitroglycerin become much more stable. You normally use a blasting cap to detonate dynamite — this creates a small …

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.
