DETERMINATION OF OPTIMAL PRE-HEATING TEMPERATURE IN CASE OF TRANSPORTATION OF CRUDE OIL AND OIL-PRODUCTS WITH PRE-HEATING
As a result of analysis of the optimization problem for non-isothermal transport of oil and oil products, subject to the conditions of real industrial process, an algorithm for finding an optimal heating temperature is suggested. The resulting algorithm is general, because it 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
As 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 calculations.
Key words: pipelines heat transfer calculation, dimensionless equations, heat transfer, Nusselt number, forced convection in pipes.

EVALUATION OF APPLICABILITY OF REIN-FORCED MINING WASTE MATERIAL TO CONSTRUCTION OF BASES OF SEMI-STEEP PIT ROADS

Possibility of uses of technogenic soil of the Nakynsky kimberlitovy field of Respukblika Sakha (Yakutia), received as a result of pit deepening, for construction of the bases of career roads of krutonaklonny congresses is shown. Thus as the stabilizer use of a surface-active preparation of "ANT" which action is directed on creation of a strong mineral skeleton from elements available in soil is recommended. It is established that application of "ANT" allows to receive constructive materials with high mechanical properties.

NATURE OF INFLUENCE PARTICLE SHAPE BACK-FILL MATERIAL OF STRENGTH THE ICE-ROCK FILLING

The 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 15% to 30% decreased by 1.5 times.

Splitting a number line into intervals the limits of which are members of primorial sequences of system allows natural numbers within these intervals to be grouped into two sets. In the interval   the first set (denoted by  ) includes prime numbers of primorial   and numbers divisible by prime factors of the primorial. The second set (denoted by  ) includes numbers that are coprime to the primorial  : unit, al primes   of the interval   and composite numbers   which are various products of the primes   and fulfill the condition that  . Cardinality of the set   is found uisng the Euler functions and equals  .
