Drilling through the lavascape. Over many aeons, volcanoes erupted from the floor of the Pacific Ocean and formed what is now known as the Hawaiian Islands. Today, those mountains of volcanic rock are providing a windfall for Blasting Technology, a US rock demolition company that is hard at work on each of the major islands in the archipelago.

The traditional method of drilling and blasting is to treat the two items as separate processes. A driller comes in to drill a hole; a blasting company puts explosives in the hole and blasts it. If you keep these two items separate, you cannot always achieve the best results. It’s not “chemical crushing,” as [Hissem] and I call it.

Rock breakage is an essential part of the mining cycle and in hard rock, this is effected by drilling and blasting. Blasting involves fracturing material by the use of specific amounts of explosives so that a predetermined volume of material is broken. Good blast design and execution are essential to successful mining operations since blasting

Drilling and blasting is one of the first operations to be carried out in a quarry to gain the material for further processing. The vital process often starts with a detailed survey of the quarry face, which will enable the explosives engineer to design the blast and to plot where the shot holes should be drilled, enabling the task to be carried out safely and efficiently.

In rock drilling, blasting, crushing, and grinding, the effective energy used in rock breakage is found to be quite small in comparison with the total input energy. For example, in rock drilling it is estimated that only 10% of the input energy is used to fracture rock, while most of the input energy is wasted as heat or other forms of energy [12].

Smooth blasting is popular, and it comes in a variant of double smooth blasting as well. Drilling costs are generally the same for the two types of smooth wall blasting but the fractured area in the remaining rock is greater in smooth blasting as compared to double smooth blasting. This lowers reinforcement costs for double smooth blasting by 50%.
