Description
Summary:In order to solve the problem of corrosion of roadway metal support materials in high temperature and humid environment, the combination of theory and material experiment, design and development of new anti-rust and tensile cement slurry and spraying technology, develop new anti-rust and tensile cement slurry, design by ourselves The multi-purpose slurry spraying machine and the new type of spray gun have been successfully applied in the concentrated air inlet of the south wing of the second mining area of our mine, and have achieved good anti-rust effect, effectively eliminating the hidden danger caused by the corrosion of the metal mesh, effectively proves that the technology is in technology and Economically feasible.
