The application of pipeline transportation in backfilling complexes poses a number of problems, the solution of which should contribute to the effective conduct of backfilling operations.

Backfill mixtures into the excavated space are usually fed by steel pipelines laid along the existing mine workings, and their routes are far from ideal in terms of the maximum required length of delivery in gravity mode.

One of the options for hydraulic transportation of bulk materials in difficult mining conditions are cascade devices that allow to feed the pulp from a great height.

Analysis of the work of hydrotransport complexes at mining enterprises shows that so far the efficiency of hydrotransport does not correspond to the technical capabilities of this type of transportation ...
