Title: Gel retarder for fire prevention and extinguishing -- Its application for spontaneous combustion of coal seams

With its unique function, gel retarder has been successfully applied to extinguish fire at coal face, roadways and stop line of upper slice extraction, and a comparably perfect set of fire extinguishing techniques has been developed. The technique gathers together characteristics of water-fixation, leak-blocking, cooling, oxidation-retarding and heat-resisting. A new agglomerating agent without amine and corrosion has been developed to replace amine-salt and acid used in the past. Gel-injection technology cooperating with the grouting system on the ground solves previous problems in which gel-injection velocity was slow and materials transport was difficult. The technique has become the main measure to extinguish spontaneous combustion in coal mines in China. The use of gel retarder as an important means of underground fire prevention will be applied more widely to prevent and extinguish spontaneous fire in coal mines.
