Blasting for Quarrying of Stones. In this method explosives are used to separate the stones from parent rock. This process is applied in case of hard stone or hard rock which does not contain any cracks or fissures. The holes are drilled in the rock and explosives are arranged in the holes and blasted with proper safety measures.
