OPTIMIZATION OF PARAMETERS OF CONSTRUCTION TECHNOLOGY SHAFTS
The
article presents the results of the analysis duration sinking cycle in
the extended part of the sinking of vertical shafts. Currently loading
and delivery are carried out mainly without the changing of buckets ,
the use of entry loader, hoppet capacity, limited winders. With
increasing depth of over 1–1.2 km, this approach leads to a significant
increase in the duration of construction sinking cycle. Loading and
delivery of the breed is a lengthy process, taking up to 50% the length
of penetration, with a single cycle is issued to 100 or more hoppet. In
this regard, improvement of the loading and egress can significantly
increase the rock penetration rate, and hence is promising. During the
construction of the skip shaft mine "Mir" the authors conducted
chronometer observation, data were obtained on the driving cycle in
1118, and 1270 cycles of lifting hoppet. Based on the analysis and
statistical processing of measurements proposed for determining the
length depending on the loading bucket, the necessity of differential
calculation, depending on the qualifications of drifters. The obtained
results allow us to improve the technology of construction barrels and
increase the speed of their construction.

FLOCCULATION OF FINE COAL PREPARATION PRODUCTS SUSPENSIONS.
Consideration
of flocculation structures formation was carried out on the base of the
extended DLVO theory with taking into account the amount of polymer
macromolecules on one particle of known diameter. It was shown that the
particles of the solid phase with diameter more than 1 μm are
flocculated by ortokinetic way for a few seconds and submicron particles
are flocculated on perikinetic way for 400–600 seconds. On the base of
the theory of fluids flow in capillary-porous media it has been
developed and experimentally validated a model describing the kinetics
of flocs mechanical syneresis. It was shown the possibility of reducing
of the water content of coal froth flotation concentrate cake by
mechanical syneresis and, accordingly, cost decrease of concentrate
thermal drying. Theoretical analysis of flocculation structures strength
for maximum shear strain state, allowed to calculate the maximum shear
yield stress depending on the diameter of the particles and the
flocculant dosage. Rheological study on coal froth flotation concentrate
showed that the nature of these suspensions without flocculants are
close to Newtonian plastically fluids, and using flocculants are
pseudoplastic properties. Experimentally obtained values of shear yield
stress for coal froth flotation concentrate not contrary with
theoretically calculated one. Also the approach for evaluating the
effectiveness of suspensions flocculation conditioning based on
experimental determination of filtration and structural-mechanical
properties of filter cakes was proposed. The obtained results allow to
predict the performance and speed of the belts. To perform the necessary
calculations in this work was the interrelation between hydrostatic
pressure and drainage time was established.

INCREASE OF THE RELIABILITY OF THE DESIGN OF STEEPLY ANGLE ELEVATING BELT-WHEELED CONVEYOR FOR HANDLING BULK LUMPY MINING LOADS
In
the previous construction of the steeply inclined belt-car conveyor
clamping of the layer of load by side belt sections was performed
directly by the pressing levers. In that case the contact between levers
and belt occurs in one or two points because of indeterminate surface
of the load layer. It’s difficult to keep the overlapping connection of
the belt side sections especially under atmospheric precipitations, when
the coefficient of friction between levers and belt is decreasing. In
the suggested construction clamping of the load layer is performed by
straps connected to the ends of levers and regulators with spiral
springs attached to the moving supports. The principle of action of the
straps with regulators is similar to the automobile safety belts. The
conveyor has the high level of construction continuity and sufficiently

STRESS STATE MONITORING OF ROCK MASS USING ACOUSTIC EMISSION EFFECTS IN ANISOTROPIC COMOSITE MATERIALS
Possibility
of using acoustic emission memory effect in anisotropic composite
materials for evaluation of stress-strain state of rock mass is shown.
The analysis of laboratory research results of common and specially

direction of uniaxial compression application and direction of
lamination (elastic inclusion plane for synthesized material) in
composites has a significant impact on the behavior of acoustic emission
during the first loading cycle, and manifestation of acoustic emission
memory effect. Thus the lowest values of the acoustic emission activity
are when such angle is 90° in the first loading cycle. When studying
memory effect it is manifested most clearly at an angle of 0° for
synthetic materials with elastic inclusion and 45° for layered
composites. A method that allows continuous monitoring of maximum

The
law of change of a relative rate of speed of passage of the ultrasonic
polarized shift wave from change of mechanical stress in firm materials
is installed. The law consists that change of mechanical stress in firm
materials, including in rocks, leads proportional, depending on
magnitude of the installed new characteristic of a firm material – the
wave module of stress – K, to change of a relative rate of speed of
passage of an ultrasonic shift polarized wave in a direction
perpendicular to a direction of act of stress. Change of a relative rate
of speed of passage of the ultrasonic polarized shift wave, with the
vector of polarization coinciding with a direction of stress, is caused
by that stress excursion in a direction perpendicular to a direction of
passage of an ultrasonic shift polarized wave calls material
deformation. The formulas are gained, allowing to define a sign and
magnitude acting and residual stresses in firm materials in certain
directions for certain baseline of measurement (Law of Kushbakali). On
the basis of the installed Law of change of a relative rate of speed of

The
paper treats the problem of formalization of the decision-making model
for selecting project options for development of solid minerals
deposits. Multi-criteria nature of the decision stems from the need to
balance the interests of a company – the subsoil users (represented by
the integral economic effect of the project) and the state – the subsoil
owner (expressed by the budget income and completeness of extraction of
balance reserves of solid minerals from the subsoil). The developed
approach is based on common features of the mining industry and its
design, consisting in the binding of the majority of design decisions to
the time and at the same time to the space, the specific character of
the dynamics of the production process, including the dynamics of mining
and providing works and equipment assignment to sites, the
irreversibility of the changes of the entire natural-technological
system state. To represent the relationships between qualitatively
different alternatives of design decisions (including mining system,
technological zoning of mine field and the opening scheme), the form of
the tree of alternatives is proposed, end vertices whereof corresponding
to fully defined project alternatives. To represent the implementation
of alternatives in time and space the form of contourless oriented graph
of states and transitions (GST) is introduced. The ways to represent
mining operations dynamics, equipment fleet composition and its
assignment to the areas of mining and providing jobs in the form of GST
are proposed. The choice of the project variant is represented in the
form of the problem of multi-objective optimization trajectory on GST.
It is substantiated that the problem of Pareto-optimization of

ALGORITHM
FOR BIAS OF COEFFICIENTS OF LINEAR AND PARABOLIC REGRESSION
RELATIONSHIPS OBTAINED USING CONVENTIONAL LEAST SQUARE METHOD IN
METROLOGICAL CERTIFICATION OF INSTRUMENTATION
Metrological
certification of calibration instruments cannot neglect inaccuracy of
calibration instruments as it is comparable to the inaccuracy of the
instruments under certification. This fact causes considerable bias
(systematic inaccuracy) of estimates obtained using the conventional
least square method. In terms of the linear and parabolic approximating
regressional relationships, the analytical expressions are derived for
quantitative estimation of bias of values obtained by the conventional
least square method for the parameters of the regressional relationships
as functions of allowable random error in measurement of input variable
(input signal). The author introduces predefined upper limits for bias
of the parameters of linear and parabolic recovering functional
regressional relationships.
Key words: regressional
relationships, least square method estimates, estimation bias, allowable
inaccu-racy of independent (input) variable measurements.

MATHEMATICAL MODELING OF ARTIFICIAL GROUND FREEZING WITH USING SOLID CARBON DIOXIDE
This
article presents a method of mathematical modeling artificial ground
freezing process in software package COMSOL Multiphysics. According to
the results of laboratory research were obtained the dependencies of
heat flow to freezing column filled with solid carbon dioxide. This data
dependencies was included in the mathematical model, as result it
allowed accurately predict the results of experiments for single freeze
pipe and a group of freeze pipes. Based on this, we suggest that this
method may be used in the design of artificial ground freezing.
Mathematical modeling allows designer to define all the necessary
parameters of freezing: freeze time; consumption of solid carbon
dioxide; total amount of carbon dioxide;, the shape of icewall with
possible influence of heat sources (heating system, pipes, etc.). Thus,
the presented method opens up opportunities for designers to expand the
practice of introducing new solid carbon dioxide freezing methods.
Key words: artificial ground freezing; solid carbon dioxide; dry ice; ground improvement; mathematical modeling.

ANALYSIS OF DYNAMICS OF FLOODING IN MINE CONSERVATION IN KUZBASS
There
are two main methods of mine conservation in Kuzbass. The first of them
is a completely flooding to spouting point, which is called «wet
method». The second way of conservation («combined method») is a
supporting the groundwater level at a certain point, which is determined
by the conditions of exception flows to adjacent operating mines as a
rule. The 15 flooding mines of Kuzbass are reviewed. There are regular
measurements of groundwater level from the beginning of their
liquidation in these mines. The periods of the active process of
flooding (from the beginning to the moment when the level of the
floodwaters rosed the surface aquifers and the process of flooding took
protracted, or to special mark point when pumping-out started in the
flooded mine) are analyzed. The results of the analysis reveals that the
conservations of the mines in Kuzbass by «wet» and «combined» methods
are specified by large fluctuations in the velocity of flooding, the
analysis of variance of which can be produced by using methods of the
theory of random functions. The groups of flooding mines are defined by
speed’s characters of flooding. The method and the results of the
analysis of variance of the speeds of flooding are given. The regularity
of the speed of the flooding new mines is revealed by analysis of all
performed measurements. This regularity has exponential character with
defined parameters and can be used for flooding predictions.
Key words: mine, conservation, the speed of flooding, the dynamics of the flooding process, correlation function, analysis.

WAYS REDUCE THE ENVIRONMENTAL IMPACT ENVIRONMENTAL COAL PLANTS RUSSIA
The
data given show that Russian coal plants are a source of trace elements
and radionuclides contamination of the environment. This is due to the
concentration of trace elements and radionuclides in ash and slag dumps
TPP and in air emissions of fly ash thermal power plants.
To reduce
the effects of trace elements and radionuclides needs a well-organized
control, as the content of trace elements and radionuclides in coal and
in ash waste and emissions of fly ash thermal power plants.
Significantly
reduce the environmental impact of coal-fired plants on the environment
is possible only with the introduction of innovative clean technologies
in the electricity and coal processing. The Energy Strategy of Russia
for the period up to 2030 is planned to increase the introduction of new
environmentally friendly and highly efficient coal combustion
technologies. This should dramatically decrease the environmental impact
on the environment coal-fired plants in Russia.
Key words: coal,
trace elements and radionuclides in coal, fly ash thermal power plants,
emissions from thermal power plants, the impact on the environment and
human health harmful impurities coal plants.

STUDY OF THE STRESS STATE INFLUENCE ON INDUCED PIPELINES MAGNETIC FIELD
The
paper studies the correlation of the steel pipe mechanical stresses
with its magnetic field parameters. Stress states in the pipe metal can
lead to the serious accidents, but they are difficult diagnosed at the
predestruction stage. This question was studied by different authors, in
particular Aginey R.V. [1] Kuleev V.G. [5, 6], Lopatin V.V. [5]. During
the experiment on Mining University basis, and the calculation in the
software package ANSYS MAGNETOSTATIC 15.0 authors obtained three
mutually orthogonal components of the magnetic induction distribution
graphs of unloaded and loaded horizontal or slightly inclined steel pipe
placed in a magnetic field of the Earth. The data are in good
qualitative correlation with the calculated distribution of the stray
fields of the magnetization, previously obtained by other authors [5].
It was found that the dependence of the field strength are complex and
increasing load leads increasing of the extrema absolute values. The
results can be used to magnetograms interpretation obtained by
diagnostic examination of pipelines, determining stress states in the
metal pipe, and good agreement of the magnetic induction experimental
and calculated values enables the use of ANSYS MAGNETOSTATIC to
calculate the magnetic field distribution under loading in more complex
cases, than considered in this article.
Key words: stress stage, pipeline, coercive force, magnetic induction, diagnostic, pipeline, ANSYS.

METHODOLOGICAL
BASIS FOR THE ORGANIZATION OF INNOVATIVE SOLUTIONS FOR THE PROTECTION
OF THE ATMOSPHERIC AIR IN THE UNDERGROUND TECHNOSPHERE CITY
The
development of large cities, accompanied by serial deterioration in
ambient air has determined the need to develop effective measures for
the protection of the technosphere environment based on advanced
achievements of scientific-technical progress.
However, in contrast
to well-established public opinion, modern scientific data show that in
closed spaces surface and underground infrastructure of the city air
pollution can be dozens of times higher than outside. In the early
1950-ies found that allergies and other chronic diseases linked to air
pollution indoors.
Today, people living in cities of developed
countries in the world spend most of their lives indoors. Therefore, the
increase in time of exposure to air pollutants causes an increase in
the number and severity of allergic reactions.
In the result of the
research conducted in the air atmosphere of the Moscow residential and
public buildings found about a hundred of inorganic and organic chemical
compounds belonging to different classes of risk. Among the volatile
chemical compounds found in the air more often than others, the most
toxic formaldehyde, phenol, benzene, styrene, ethylbenzene, toluene,
xylene, aldehydes, acetone, ammonia, ethyl acetate, oxides of nitrogen,
oxides of carbon. In addition, in the air of buildings contains aerosols
of heavy metals: lead, cadmium, mercury, zinc, Nickel, magnesium,
chromium and other
The article presents the results of the
development of the fundamental principles of the organization of
