Equipment to improve drilling, blasting operations

Brunner & Lay developed the Arrow drilling system to allow modern, high-powered rock drills in surface and underground applications to produce precise holes. The Arrow provides less bending stress on drill string and reduces hole deviation to improve the service life of the string. According to the company, this saves fuel and wear and tear on the drill.

Drilling and Blasting

Mining crushed stone generally requires drilling and blasting of solid bedrock (also referred to as ledge or ledge-rock), which breaks the rock into rubble of a size suitable for crushing. Crushed stone and sand and gravel commonly are obtained from dry pits or quarries, but in some settings may be mined from water-filled excavations using

Drilling and Blasting in Underground Mining

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%.

Best practices: Drilling and blasting : Pit & Quarry

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.
