SMS: A Site Mixed Slurry Explosive

gn: justify">3. Lowest energy product say, base product, in both SMS and SME has energy of about 640 Kcal/kg. Every one percent addition of Aluminium to a base SMS product increases energy by roughly 40 Kcal/Kg. Thus a SMS product with say 5 percent Aluminium shall have energy of approximately 840 Kcal/kg. In case of Emulsions Explosive, energy increase is normally achieved by addition of AN in prill form. Every one percent addition of AN prill to the base SME product increases energy by roughly 5 Kcal/kg. Thus a SME product with say maximum of 20 percent AN prills (addition of AN prill more than 20% create problem in pumping) shall have energy of approximately 740 Kcal/Kg which is not sufficient to break very hard rocks like massive granite & highly abrasive quartzite existing at Malanjkhand Copper mine.

4. Thus, there is
