Emulsion Based Cast Booster - A Priming System

The mineral industry is leading towards a technology driven optimization process. Drilling and blasting are such unit operations in a mine, which can alter the balance sheet of the mine if not planned properly. The development, improvement and utilisation of innovative technologies in terms of blast monitoring instruments and explosives technology are important for cost effectiveness and safety of mineral industries. The ever-growing demand of mineral has compelled the industry to adopt mega opencast projects with big equipments. This has necessitated use of few hundred tonnes of explosives in each blast. The bulk delivered fourth generation explosives has solved the problem of explosive loading to a large extent. The priming of bulk delivered explosives in Indian mines uses the conventional PETN/TNT based cast boosters. As the conventional cast booster possess safety problems in terms of handling and use, so Indian Explosives Ltd., has developed an emulsion based cast booster (Powergel Boost).
