【 摘 要 】

The most effective technical solutions have been those that provide for the supply of substances used for extinguishing to the combustion zone of the rock dump. When quenching rock on the rock dump is proposed injection (blowing) in a dry extinguishing agent, represented by crushed vermiculite (hereinafter referred to as the extinguishing agent), in pure form or in a mixture with alkaline substances. The problem of developing methods of extinguishing rock dumps, characterized by low cost and high efficiency, in the absence of additional environmental pollution is very relevant. The technology of suppression of waste rock dumps include the injection of suspended particles of vermiculite in contrast to the clay slurry or solution (suspension) of antipyrene. This allows to penetrate into the surface layer of the middle and upper part of the blade and insulate its lower part with non-combustible material.
