Vibroactivation of Hardening Backfill Mixtures during Transportation over Extended Distances

Abstract—The possibility of utilization of environmental protection technologies for void filling with hardening backfill mixtures without the construction of backfill complexes and surface transport pipelines is justified. Quantitative parameters for nature and resource conservation are determined with allowance for the cost of land taken out of circulation during the construction of backfill facilities on the surface. A model for optimizing the transportation technology of mixtures to their placement sites along underground mining workings over extended distances is formulated. A typology of activation methods for hardening mixtures based on their structural design is proposed. Permanent activation of components during the production and transportation of hardening mixtures is shown to decrease environmental damage using transporting mixtures through pipelines in underground workings without the need to construct backfill facilities on the surface.
