  • Process for strengthening geological formations
    Patent number: 4792262
    Abstract: The present invention is directed to a process for strengthening geological formations in underground mining or other operations introducing into the formation which is to be strengthened mixtures of a polyisocyanate component (a) and a polyol component (b) which react together to form polyurethanes, characterized in that the polyol component (b) is based on mixtures of (i) organic polyhydroxyl compounds having hydroxyl numbers of about 100 to 600 and (ii) dihydric alcohols having a molecular weight of 62 to about 150, component (ii) being present in an amount of about 0.01 to 20% by weight, based on the total quantity of component (b).
