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].

the drilling process measures like drill hole accuracy (drill hole position and depth), the blasting process measures like the powder factor, the charge length, the amount of explosives used per charge (blast) will be considered and the overburden fragment size will be determined to improve productivity and cost.

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%.

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

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.
