Main scientific and practical results of hardening stowage mixture components activation efficiency improvement in
vibration pipeline transport plants for worked out area filling are introduced on the basis of new technologies and hardware,
which can reduce transportation energy consumption down to 0.25–0.30 kW/h on 1 m3
of mixture, increase the length of
pipeline section up to 150–200 m, capacity – 1.8–2.0 times, artificial massif strength – in 20–25%, provide reliable
mixtures delivery, standard cone settling of which constitutes 10–13 cm, which contain by mass 0.10–0.35 dispersed
particles and solid concentration 0,80–0,85 for distance which exceeds vertical flight height in 20 times, and total mixture
removal out of the pipeline under water discharge 3–5 m3
for one sluice. The ratio of flexible supports rigidity is obtained
in horizontal and vertical surfaces, equal to 1.2–1.4, under which the most efficient trajectory of pipeline motion
is obtained under circular exciting force of a vibration generator. The efficiency of elliptical vibrations of a pipeline impact
on the reduction of hardening stowage mixture motion resistance is shown.
Key words: hardening mixtures; components activation; stowage works; vibration machine; pipeline transport.
