The primary technique of rock fragmentation followed in mining is blasting. This is perhaps due to various benefits like economy, efficiency, suitability, and applicability [].However, only a part of the explosive energy (15–20% of the total explosive energy) is used to break rocks while the rest scatters into heat, vibration, sound, and vibration [2, 3].
