Abstract: In article questions of improvement of systems of pipeline transportation of the cast hardening stowage mixes, for a stowage of the fulfilled excavations of the operating mining are considered. The new direction of development of technical means of the stowage mixes intended for ensuring safe and uninterrupted delivery with the lowered water content connected with use of the special hydrodynamic feeders and activators established on the stowage pipeline that creates conditions for maintenance of standard rheological properties of fluidity of stowage mixes at their pipeline transportation is offered, and provides essential increase of durability and speed of сreate of the stowage massif, and, as a result, increase of intensity and safety of carrying out underground mining operations.
In article the researchers conducted in this direction, connected with establishment of influence of constructive characteristics and operating modes of the offered hydrodynamic activators on the main rheological characteristics of the cast hardening stowage mixes possessing plastic properties are described that significantly complicates their transportation by usual delivery systems. Presented the original patented designs of activators and feeders providing high efficiency of restoration of rheological properties of stowage mixes at their transportation on the underground stowage pipeline are offered.
