Consolidation of geological formation in underground coal mining using a polyurethane-forming mixture of polyol and polyisocyanate components with an added fatty acid triglyceride without isocyanate-reactive groups

摘要

Consolidation of geological formations in underground coal mining by applying a reaction mixture containing a polyol component A and polyisocyanate component B through bore holes, which react to form a polyurethane. Fatty acid triglycerides containing no isocyanate-reactive groups are added to component B.
