Quarrying Stones for Construction Works
· Blasting for Quarrying Stones. This method, explosives are used to exfoliate the stones from parent rock. This process is done in case of a hard stone or hard rock which does not contain any fissures or cracks. The holes are drilled in the rock and explosives are arranged in the deep holes and blasted with proper safety measures.
