Rock Drilling
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 Influence of Parameters of Drilling and Blasting Operations on the
crushing of rocks by an explosion. Imitation calculations confirmed that the rational degree of crushing depends mainly on the operational parameters of the excavator, the blockiness of the exploded rocks. The rational degree of crushing Z r depending on these factors can be calculated by the formula (4) (Kovalev and Litvin, 2012): 𝑍𝑟= 1 +

Typical Blasting Methods for Structural Engineering Operations
Blasting is the process of cracking rock material by using a small amount of explosive substance so that the rock is destroyed into several pieces. In the past, black powder and dynamite were used for the explosive process. Blast design and execution are important for successful rock removal operations. The use of excessive explosive material at the blasting site may cause unwanted caving
