All the analyzers of weight mass in flux single out and analyze a part of the material of a flux, which is equivalent to
the sample selected with the method of longtitudal sections. Such sampling is equivalent to sampling from a well-stirred
massif where inaccuracy depends on the mass of a sample. The analyzed mass depends on the conditions of the
analysis and can be hundreds of grams for pulps, whereas for lumpy products – kilograms. Pit sample is represented
by the mass of the material analyzed in the fixed period of the analysis, when the quantity of pit samples is the function
of break duration between the measurements (analyses). Random inaccuracy of pulp analyzers, depending on the
mass of the analyzed material, can be associated with inaccuracies acquired in sampling with the method of longtitudal
sections. When analyzing a large amount of pit samples, random inaccuracy can be significantly decreased. Random
inaccuracy of analyzers of ore fluxes at the conveyors, depending on the mass of the analyzed material, is high and
becomes acceptable only under averaging of a large amount of pit samples. Under the use of the method of longtitudal
sections, systematic inaccuracy can be totally excluded.

Key words: analyzers of ore fluxes; the method of longtitudal sections; sampling inaccuracy.

Today the most perspective type of minerals transportation to the surface is a skip pipeline pneumatic elevator, where
containers in the shape of cylindrical capsules move along the smooth pipes at high speed. On the capacity equal to
the cable ways, pneumatic elevator possesses lower prime cost and allows significantly reducing costs for shaft sinking,
construction of pithead buildings and structures. In two-pipe installation one pipeline is designed to ascent, the other – to
descent skips. Mathematical model including the equations of loaded and unloaded containers kinematics is required to
design the systems of skip pneumatic elevator. Special interest is attracted by the functions of speed and acceleration
of the container which descends down the pipeline under its own weight. A body moving in gaseous medium creates a
zone of increased pressure, the value of which depends on the speed of the body and the speed of pulse propagation
in the medium. Based on the assumptions of continuum mechanics, theoretical dependences are acquired for speed,
acceleration, and displacement of a skip in the period of its sinking in descending pipeline. It has been stated that
kinematics of unloaded skip differs significantly from free fall. Estimative calculations have been fulfilled towards
the particular values of the mass of the container and the diameter of the pipeline. The formula has been worked out
for the value towards which the speed of the container asymptotically verges. Curves have been built, which illustrate
behavior in time of acceleration, speed, and displacement of “falling” skip.

Key words: shaft; skip; main ascent; pneumatic elevator; pipeline; kinematics; aerodynamics.

Design and operation principle of stand unit for testing stages of electric-centrifugal pumps (ECPs) are described.
Methodological framework for conducting accelerated life testing of ECPs is set out, which make it possible to fulfill
qualitative assessment of the service life of stages of submersible electric-centrifugal pumps of various designs.
Examination of experimental and pre-production ECPs stages samples operation at the laboratory stand at artificially
created and severe conditions of the submersible pump exploitation provides identification and timely elimination of
technological and structural defects of items on test. At that, material and time expenditures for the laboratory research
are significantly lower than for the implementation of field tests. The use of verified and high-precision measuring
instrumentation in the process of ECPs testing makes it possible to determine hydraulic and energy characteristics of
existing and experimental stages of centrifugal pumps stages in real-time mode.

Key words: electric-centrifugal pump; oil production; stand unit; accelerated life testing; reliability.

New economic conditions lead to an expansion in the use of program-driven manipulators. Their constructive schemes
should meet the principles of universal designs, modeling and design methods in 3D. An example of calculation and
visualization of power and design parameters based by the example of table processors is considered. This makes it
possible to explore the features of the manipulators and the possibility of their testing with the typical software based on
Adams. The peculiarities of calculation of parameters for providing a given trajectory with the positioning of the construction
carried by the manipulator are revealed. And the results confirming the possibility of creating universal designs are
obtained. The peculiarities of the stress-strain state of power hydraulic cylinders and the formation of asymmetric contact
zones at the collar bush and piston are studied at work with eccentricity, which will allow solving a number of problems of
designing manipulators for difficult-extracting mineral deposits development systems.

Key words: manipulator; hydraulic cylinder; equilibrium equations; contact pressures.
