The article provides an assessment of mining operations in underground mines which apply backfill systems, as well as the volume of enrichment waste accumulated during the exploitation of ore deposits. The use of high-quality cement and expensive inert fillers by many mining companies significantly increases the cost of backfill, while the technologies for increasing the activity of the binder are only partially used. The adoption of low-quality binders (cement and milled granulated slags), the investigation of new economically advantageous technologies for producing filling mixtures, as well as the use of binders and fillers, which can be used as tails of enrichment waste, will promote the spreading of backfill systems. In the practice of mining, it is an urgent task, which should be solved. This solution will significantly expand the raw material base of many mining enterprises; it will also increase their efficiency and address environmental protection issues. The conditions and regularities of increasing the reaction properties of many dump products, changing their rheological properties in time, as well as ways to create, and maintain the activity of the filling mixture during its preparation and pipeline transportation, remain insufficiently studied.

We also consider the concept of improving the systems of pipeline transportation of cast hardening of filling mixtures to ensure reliable and uninterrupted delivery of the obtained backfilling mixtures with the reduced water content. It is associated with the use of the special hydrodynamic actuators mounted on a backfilling pipeline. As the activating devices the original patented designs of activators providing high efficiency of restoration of rheological properties of stowage mixes at their transportation on the underground stowage pipeline are offered and described.

Based on the theoretical justification of the proposed design solutions, we can conclude that the proposed trigger device will provide effective homogenization and activation of the material hardening mixtures on the basis of the tailings while reducing metal consumption, energy consumption and processing time.

Keywords: mining activity; mining technology; backfilling mixture; backfilling works; pipeline transport.
