More Information
Summary:The authors propose and analyze the method of soft rock reinforcement by injection of bicomponent organomineral resin with compressed-air blowing of reagents deeper in rocks. The bench tester structure, the polymeric formula, the composition and resin properties, as well as the treatment procedure are presented. The tests are described. The scope of the discussion encompasses the results of the permeation tests, strength tests and the analysis of structure of voids in sand samples after their stabilization using the proposed approach and the standard single-component resin injection. The advantages of the successive injection include the chemical treatment coverage, specific consumption of agents and the increased strength.
