Ensuring Corrosion Resistance of Injection Solutions for Grouting of Jointed Rocks in Underground Developments of Cryolithozone

Results of pilot studies on development of cement injection solutions possessing anticorrosive properties in sodium-chloride brines in the conditions of underground “Mir” mine are given in the article. It is shown that the developed compositions of injection solutions on the basis of sulfate-resistant and aluminous cements conform to requirements of the project to material and technology of injection, provide curing at lowered temperature of breeds and more high corrosion resistance to brines.
