Abstract

Deflagration or slow decomposition of permitted explosives in underground coal mines is considered to be dangerous, initiating research activities in different countries on the subject. In India too the phenomenon has been a subject of research at Central Mining Research Institute, Dhanbad. From the initial studies with slurry, NG and emulsion explosives under varying experimental conditions favourable for an explosive to undergo deflagration were identified and reported. With the reports of few incidences of deflagration of some NG based and slurry permitted explosives in underground coal mines, it has become all the more necessity to adopt preventive measures towards reoccurrence of such hazards. Studies were conducted with some NG-based, slurry and emulsion permitted explosives of different manufacturers in different laboratory set-ups employed in different countries and a new, safe, sensitive and discriminatory set-up for standardization of method and condition for assessment of deflagration propensity of Indian permitted explosives.
