风化

The physical characteristic of weathered lamprophyre has impenetrability and nonhomogeneity, however, the YDS epoxy resin possesses initial viscosity, strong affinity to mediums, excellent permeability and good ageing property. After chemical grouting, the rock mechanics characteristics are improved greatly and can meet the design requirements, it indicates that lamprophyre can be grouted by YDS epoxy resin.
