Inhibition of coal oxidation for preventing coal fire during surface mining involves treating coal surface exposed to air with composition of water-soluble cationic polymer and anionic and/or nonionic surfactant as wetting agent

摘要

Inhibition of coal oxidation in a coal pile involves coating all surfaces of coal exposed to air with an oxidation inhibiting composition (C1) comprising a water soluble cationic polymer (a), and a wetting agent (b) selected from anionic and/or nonionic surfactant.
