Estimation of Optimum Burden for Blasting of Different Rock Strata …
Two different approaches have been used in this paper for computation of optimal burden of different rock strata of an Indian iron ore mine. The first approach is based on assessment of rock mass properties and explosive properties for the blast. The assessed properties are put in different empirical equations of Kuz-Ram model.
