Description

Technical Field

[0001] The invention belongs to the technical field of building construction equipment, and in particular relates to grouting equipment for goaf area construction. Background Art

[0002] Goafs are "holes" created beneath the surface by human excavation or natural geological movements. The existence of goafs poses great safety issues to mine production, as both personnel and mechanical equipment may fall into the goaf and be injured.

[0003] The mainstream treatment methods for the current goaf include caving, filling and sealing. The filling method uses waste rock stripped from the open-pit on the surface, waste rock from underground mining or tailings from ore dressing as the main filling aggregate, and the filling material is filled into the goaf underground by gravity (or pressure) through the boreholes, skylights or filling pipes in the goaf. Using filling materials to support the surrounding rock can slow down or prevent the deformation of the surrounding rock to keep it relatively stable.

[0004] However, in the existing filling method, a single-point grouting method is basically adopted, which results in that during the grouting, the slurry is injected from a single point and then flows to other areas, which easily causes uneven distribution of the slurry and affects the filling quality.
