Crynodeb

In India, till now ANFO consumption has been limited to non-coal mining sectors. The paper attempts to address the possible reasons for the neglect so far towards ANFO usage in Indian coal mines in spite of its high potential. An analysis of globally recognized empirical formulas has been done to see the overall economy of ANFO among different strata conditions and charge alternatives in respect of powder factor, blasting costs and mean size fragmentation distribution. Attempt has been made to quantify the contributions of high heave energy of ANFO towards optimum fragmentation from the studies of ANFO performance in similar strata of the non-coal sector. The study has been done for effective blast design and explosive selection for Shovel and Dragline benches of Indian surface coal mines in different geotechnical conditions. The outcomes of results justify the potential of ANFO and its selection by mine operators worldwide.
