The composition of explosives is balanced chemically to produce the desired effects in blasting. Note: the orange fumes sometimes seen in open pit blasting indicate that there is water in the blastholes. The water desensitises a proportion of the fuel, upsetting the oxygen balance and resulting in the production of nitrous oxides. 4.1 ANFO

Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is …
