Blasting Design In Indian Limestone Mines

  • Prediction of blast-induced flyrock in Indian limestone

    Oct 01, 2014· Rock fragmentation and over break are influenced by the joint sets. The blast design can be improved by review and analysis of past data of the blasts conducted in the mines (Bhandari, 2011, Parihar and Bhandari, 2012). Flyrock due to blasting in opencast mines is complex in nature as it is a random phenomenon.
