Blasting using permitted P5 category explosive having higher air gap sensitivity with spacers for higher output

ABSTRACT

In India, three categories of permitted explosives namely P1, P3 and P5 are approved for use in underground coal mines. P1 category is the strongest while P5 is the weakest and safest among permitted explosives. Nitro Glycerine based explosive was banned in India in January 2004 and only slurry or emulsion products are manufactured in India.
