AI Technical Summary

Technical Problem

Existing organic polymer grouting materials for mining have safety hazards such as high cost, corrosiveness, flammability, and easy aging. Moreover, the preparation process is complicated and it is difficult to disperse and gel quickly and evenly in deep mining.

Method used

Magnetic nanoparticles with different coating thicknesses were prepared by co-separation extraction and used as raw materials for two-component grouting material. The grouting material was produced by a reaction process using multiple stirring devices connected in line. After mixing, the grouting was carried out under the assistance of a magnetic field, which optimized the gel time and impermeability of the grout.

Benefits of technology

This method enables rapid and uniform dispersion of magnetic nanoparticles under a magnetic field, optimizes the gelation time and impermeability of the slurry, improves the safety and production efficiency of the grouting material, and reduces the preparation cost.
