Optimization of Blasting Parameters in opencast Mines

Drilling and blasting are the major unit operations in opencast mining. Inspite of the best efforts to introduce mechanization in the opencast mines, blasting continue to dominate the production. Explosives contribute currently about 5% of the direct cost of production and if the aggregate cost of drilling and blasting is taken together, this may go as high as 30% of direct cost of
