Mining play’s major role to development of nation, mining is defined as extraction of valuable minerals (or) ore from the earth crust for benefit of mankind in safe and economic manner. India is a developing country it needs valuable minerals to improve economic wealth. In India most of the mining operations are run by open cast mines. In open cast mining work is mainly involves drilling and blasting operations. Mostly drilling and blasting operations are followed except in smooth rock, where bucket wheel excavator [BWE] used. The main problems a raise in drilling and blasting are high capital investment, time taking process and less powder factor. This loss depending on parameters like geological conditions of the mineral, nature of ground, strength and type of drill bit to be used in drilling. And drilling pattern, explosives used for blasting also involved. It concludes optimization of drilling and blasting necessary to improve the powder factor, production rate, improving fragmentation of rock, reduction of ground vibration, reduce cost of drilling and blasting. The main optimization technique achieved by help of following factors. Those are spacing, burden, bench height, drill hole diameter, depth of the drill hole and characteristics of explosives (VELOCITY OF DETONATION & DENSITY). In this work we studied on different types of optimization parameters and choosing the best techniques among the following techniques.

DRILLING, BLASTING, EXPLOSIVES, VELOCITY OF DETONATION.
