In rock blasting in mines, achieving desired fragmentation is the main objective of blasting. Therefore, a small portion of the explosive energy is used to fragment rock mass, and a considerable part of the energy is consumed for flyrock, airblast, ground vibration, fragmented rock movement, and heat.

After the explosion, the broken material is cleared and, if the drilling and blasting occurred underground, the tunnels created by the explosion are fortified to allow for safe human entry. Alternatively to explosives, gas pressure blasting pyrotechnics can also be used to displace the rock for excavation.
Drilling machinery, equipment used to drill holes in the ground for such activities as prospecting, well sinking (petroleum, natural gas, water, and salt), and scientific explorations. Drilling holes in rock to receive blasting charges is an operation in tunneling, mining, and other excavating.
