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.

It has been shown that the practicability of mining equipment performance estimation at Russian mining enterprises
nowadays is conditioned by the increase of the park of outmoded and physically outdated machines and equipment.
The use of the methods of engineering diagnostics of mining machines allows obtaining and processing information about
the condition of units and aggregates of every piece of equipment. The availability of such information allows setting
optimal interrepair time or forecast remaining life time of units and details, swiftly determine maintenance requirements of
mining machines and equipment, check maintenance quality and control the performance of the park of mining machines
at the enterprise. The most preferable method of mining equipment performance control is the method of vibrodiagnostics.
The use of the method of vibrodiagnostics to determine actual performance of mining machines allows increasing the life
time of equipment operation by means of including operations of removal and disassembly.
Key words: expert inspection; performance monitoring; technical diagnostics; technical life time; nondestructive testing
methods; defect; vibrodiagnostics; vibrational loading; harmonics.

and constructive parameters of rope operating device precise recommendations over the creation of advance designs
have been worked out. The results obtained can be used in stone milling and stone working branches of industry; they
can also be used by scientific-research institutes and experimental design bureaus, which design and create advance

Recommendations are worked out over the use of rational parameters of blasting in restrained medium under the use of
emulsion explosives in production. The use of the developed parameters of breakdown and retaining wall helped to
provide the security of rock massif geological structure, increase the coefficient of efficiency for explosives, reduce
preliminary-recovery operations when blasting at a bench, and increase security and capacity of loading – hauling
equipment. Under significant thickness of deposit, the method of discrete blasting of ore and enclosing rock with natural
“screening” is advisable, which consists in the use of advantageous structural-geological and mining-engineering factors
as natural borders of blasting. In order to calculate the width and the height of blasted rock breakdown under downhole
charges explosion with the use of emulsion explosives the formulae are worked out, which include the main parameters,
which determine energetic characteristics of explosives and physical-mechanical properties of rocks.
Key words: drilling and blasting operations; blasting in restrained medium; safety of rock massif geological structure;
retaining wall height; retaining wall width; discrete blasting of ore; structural-geological factors; mining-engineering
factors; emulsion explosives.
