Optimization of Blasting Parameters in opencast Mines

2012-7-5  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. Therefore to cut down the cost of production optimal fragmentation from properly designed blasting pattern has to be achieved.

Benches may be designed and carried forth with morethan one face so that simple blasting patterns can be used to remove the rock. In the illustration thatfollows (Figure 8-4) shows a typical bench cut with two free faces and fired with one delay per row.
