allows to find the optimum heating temperature for different optimal
criteria. In the solution obtained corrected the shortcomings of
existing techniques, including a major drawback as the search for
solutions at a fixed flow rate. The criterion of maximum benefit, which
allows to get the maximum benefit of transporting crude oil and
petroleum products is suggested.
Key words: "hot" oil pipeline, optimal temperature of preheating, nonisothermal flow, energy saving.

CORRELATION EQUATIONS OF HEAT TRANSFER IN CAST OF TRANSPORTATION OF CRUDE OIL AND OIL-PRODUCTS WITH PRE-HEATING
a result of analysis Miheev’s correlation equations for Nusselt number
calculation in case of forced convection in pipes, with the help of
multiply linear and non-linear regression and statistical analysis, new
correlations are suggested. Using new correlations in heat transfer
calculation, there is no need in iteration solver. The equations for
transition flow regime were formulated. This makes it possible to take
account of transition flow regime in heat transfer and hydraulic

NATURE OF INFLUENCE PARTICLE SHAPE BACK-FILL MATERIAL OF STRENGTH THE ICE-ROCK FILLING
character of the influence of filler particle shape on the strength
characteristics frozen water rock mixtures. The content of particles of
different shapes in the exploded rocks of the mine Badran, used as a
placeholder frozen backfill. Results of tests frozen backfill samples
with different contents of lamellar particles (flaki-ness) and needle
forms on the compressive strength. Found that the tensile strength of
the material on frozen backfill uniaxial compression with increasing
content of lamellar particles (flakiness) and needle forms filler with
