DEVELOPMENT OF THEORY AND MODELING OF PROCESSES OF ARCHING IN THE VICINITY OF A TUNNEL
Geomechanics
solves many practical problems. But there are two main, we can say
classical tasks of geomechanics is the problem of the stability of mine
workings and the problem of earth surface strike shift with the
development of mining operations. The first problem appeared from the
beginning of mining, the second much later, when education developed
space has led to a significant displacement of the overlying rock
masses. Development of technology of urban underground construction over
the past 50 years aimed at minimizing displacement of the overlapped
arrays. However, the task of destruction of soil in the mine working
arch or the task of svoeobraznyi remains unresolved to date. The paper
presents a formula for determining the load on the tunnel lining.
Key words: geomechanics, physical and technical basis, model, production, finishing, the calculated circuit voltage offset load.

THE
ESTABLISHMENT OF THE CRUSHING AREA RADIUS OF FRACTURED STRAINED MASSIF
DESTRUCTION DURING EXPLOSION OF TWO PARALLEL CONTIGUOUS CHARGES OF
BLASTING COMPOUNDS
Analysis of technical literature has shown
that during explosion of parallel-contiguous charges of blasting
compounds mathematical formulas for determination radius of destruction
of fractured massif that defines the most important parameter − the line
of the least resistance are absent.
On the basis of energy theory of
deformation and destruction of fractured rock massif by explosion we
solved a classic problem of interaction of deformation waves from two
charges of blasting compounds exploded simultaneously. According to this
theory destructive waves of voltage lose the main part of energy on the
nearest to charges natural flaws and the destruction of outlying joints
occurs as a result of deformation and fracture by the action of
detonation products. In other words, the wave of charge deformation,
that is posed as successive displacements of joints followed by
inelastic deformation of array on the natural joint’s edges together
with its elastic strains and deformation, spreads in the massif.
Practice
has shown that classical solution during determining the line of the
least resistance underesti-mates this value. Another theoretical problem
is solved taking into account effect of massif elastic response, as a
result of its pressure between two blasting holes. Accounting for the
elastic reaction effect makes it possible to increase the line of least
resistance at the same results of explosion. We gave the numeral values
of massif’s crushing area radius with different variants of the
calculation, which prove the need to consider the effect of elastic
massif reaction.
Key words: parallel-contiguous charges of
blasting compounds, radius of crushing area, fractured strained massif,

DETERMINATION
OF BREAKING ZONE OF STRAINED FRACTURED ARRAY DURING SIMULTANEOUS
EXPLOSION OF SEVERAL PARALLEL CONTIGUOUS CHARGES OF BLASTING COMPOUNDS
During
extraction of low powered ore bodies ( power to 3,0 m.) using cross
options of mining method, selective breakage of flat deposits and ore
preparation for underground leaching, we use breaking method of parallel
contiguous charges of blasting compounds more often. At explosion of
several contiguous holes the most important parameter is a radius of
controlled crushing zone of fractured array transversely to line, which
connects the charges of blasting compounds. This article considers an
action of 3 and more parallel contiguous charges of blasting compounds
on the basis of energy theory of explosive attack on strained fractured
rock array. Theoretical formula for calculating radius of zone of
controlled crushing during simultaneous blasting of series of charges
transversely to flats was formed, the line of the least resistance was
determined as well. We conducted a series of technical experimental
explosions at sublevel breaking of low powered ores with assessment of
coarseness of grading by photo planimetric method in conditions of
underground uranium mine № 1 PJSC PIMCU. Comparison of experimental
researching results and theoretical calculations (on the basis of
parameters of drilling and blasting works and a middle size of a piece)
points on their favorable similarity.

In
the basis of the developed models of geomechanical state massif,
contain of mine working iand geological violation, are two methods – the
method of fictitious loads and displacement discontinuity method. The
method of fictitious loads describes the boundary conditions on the
contour generation, and the displacement discontinuity method formulates
the conditions on the banks of the violation. Geological violation is a
narrow gap with a filler of resilient material with desired
characteristics of stiffness in compression and shear. Within the model
the conducted research of the stress state of rock mass around mine
working and crevices, in particular, the diagrams of the normal stresses
in the roof of the mine working and the soil cracks. The results of
these studies show that with certain distances between them in the array
experience significant tensile stresses. These stresses in the roof of a
drift, and in soil cracks are acting in the horizontal direction. The
sizes of the zones of discontinuity in the array that occur around a
single mine working, differ slightly from the sizes of similar zones
formed in an array around an excavation and cracks. The maximum
difference of values of the coefficient of dislocation for these cases
is about 7 percent.

REGULATORY FRAMEWORK FOR MINING EQUIPMENT QUALITY AND SAFETY CONTROL IN DESIGN AND CONFORMANCE EVALUATION
This
work presents the results of investigation of the structures formed by
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.

MODIFICATION OF MINERAL PARTICLE’S PHYSICAL PROPERTIES IN SEPARATION PROCESSES
Modification
of mineral particle’s physical properties in separation processes is a
way to increase their efficiency. Aggregation and coagulation of
fine-disperse particles result in decreasing their hydrodynamic
resistance coefficient, and increase thus extent of their contrast in
gravity and magnetic concentration processes. The CFD model of radial
thickener has been designed with using population balance equations in
ANSYS software for describing coagulation processes. Computational
experiments in a virtual laboratory bench have revealed dependence of
suspension coagulation velocity on its viscosity and possibility to
decrease reagents consumption through changing viscosity of suspension
thickened. The experiments gave also shown that particles aggregation
allows increasing their precipitation velocity up to 2 cm/sec.

ECONOMICAL AND THEORETICAL ASPECTS OF MARKETING AT THE MINING ENTERPRISES
In article single economical and theoretical questions of marketing at the mining enterprises are considered.
It
is noted that at full realization of criteria of marketing requirements
as seller, and the buyer have to be met. Requirements of the seller and
the buyer of production have to be provided on the basis of efficiency
of business which main condition expresses equality of the discounted
cost of future net income of the buyer (the enterprise uses cars and the
equipment for production of concrete production) and investments,
expenses, expenses of the seller (manufacturer of cars and the
equipment).
Effective development of market structure is carried out
in the direction of dokhodooriyentirovanny economy.
Dokhodooriyentirovanny economy – economy with release and realization of
competitive production, that is the economy focused on continuous
introduction of innovative solutions by production of production
delivered on the market. The Dokhodooriyentirovanny economy defines a
tendency in approach to market structure of the perfect competition. To
Dokhodoorintirovanny economy use of high-performance cars and the
equipment, a high salary of workers, increase in volumes of release and
delivery to the market of the realized production is characteristic. The
aspiration to decrease in prime cost of unit of products due to
increase in production is peculiar to Dokhodoorintirovanny economy.
Marketing
activity is especially important in the conditions of low competitive
economy. Low competitive economy – the economy which is on production
and delivery to the market of production in insignificant volumes and
the limited range. Such economy has to seek for achievement of level of
dokhodooriyentirovanny economy. In low competitive economy the
enterprises of market structure of the imperfect competition (monopoly, a
duopoly, a monopsony, an oligopoly) function. To low competitive
economy use of low-productive cars and the equipment, a low wage of
workers, use of cheap materials is characteristic. The aspiration to
economy of expenses and expenses without attraction of new technology,
new high-performance equipment due to decrease in outputs is peculiar to
low competitive economy. For low competitive economy existence of
growth of prime cost of a unit of production is characteristic.
Functioning of the enterprises of low competitive economy demands
performance of strict ratios in change of rates of the main technical
and economic indicators of production economic activity: prime costs of a
unit of production, labor productivity and volume of production; costs
of production and profit.
Key words: economical and
theoretical aspects, marketing, mining enterprises, market of the

INTEGRATED DEVELOPMENT OF NATURAL RESOURCES ON THE BASIS OF PUBLIC-PRIVATE PARTNERSHIP
The
article outlines forms of interaction between regional government and
business in implementation of public-private partnership (PPP) in field
of socio-economic development of territories. It is shown that
negotiated agreements on social and economic cooperation are not
"purely" PPP projects.
Factors affecting development of cooperation:
lack of methodologically and theoretically elaborated economic vision
and strategy for integrated development of mineral resources (IDMR);
export commitment to "ready", borrowed technology development of PPP
projects; lack of methodology and methods for evaluation of regions'
readiness to use PPP projects in the field of IDMR; lack of methodology
and methods for selection of potential PPP projects in IDMR field and
evaluation of economic and social effects of their implementation;
unworked federal and regional legislation governing partnership between
business and government in general, and particularly in IDMR field.
There are conclusions on «usefulness» of such projects for regions
development in integrated development of mineral resources. Development
methodology and theoretical concept of interdisciplinary research of
mineral resources complex development in the Russian Federation with use
of methodology and techniques of reasonable specialization (Smart
Specialization) are proposed; creation of methods to predict development
of advanced production technology in Russia on basis of developed set
of science-metric characteristics, as well as methodology and techniques
of assessment of territories readiness to implement PPP- projects in
the IDMR sphere in Russian regions.

ON CALCULATION OF FOUNDATIONS ON SWELLING SOIL WHEN MOISTENED WITH HOT WATER
The
problem of calculating the foundations of buildings on the swelling
clay soils when wet with hot water. The values of contact pressure upon
swelling PH(x) under the sole base facilities for moistening water T =
20°C and T = 40°C...80°C. It is proposed to adopt diagrams swelling
force when moistened in the form of a square parabola dome swelling and
add to the load of its own weight structures as the equivalent load of
contact pressures PH(x).

INTEGRATED GEOMECHANICAL MONITORING IN URANIUM MINES IN TRANSBAIKALIA
In
focus is the problem of control and prediction of movement and
rockburst hazard in uranium mines in Transbaikalia. Experience of
Priargunsky Mining and Chemical Works in the area of integrated
rockburst hazard monitoring in underground mining in Streltsovsky ore
field featured with complex geomechanical situation and high rate of
injuries on deep levels is described.
The article presents automated
rock pressure control system ARPC, including network of underground
geophones and digital transducers for continuous recording of dynamics
of mechanical processes.
For continuous seismo-acoustic monitoring
and regional rockburst hazard forecasting, the author describes
automated wide-range rock pressure control system AWRRPC—PROGNOZS
developed at the Institute of Mining of the Far East Branch of the
Russian Academy of Sciences. The geomechanical monitoring system enables
detecting increased stress zones in rock mass and higher energy
micro-displacements of rock blocks in the course of stoping and allows
visualizing such migrating sources and places of seismo-acoustic
activity.
The author describes systems meant for remote monitoring
of deformation in tunnels, mines and subways as well as for preset-time
data collection and storage in non-volatile memory of SMD-KM unit of the
system with option of data transmission and live browsing on a PC. The
system supports round-the-clock operation in the mode of low energy
consumption. This method allows real-time detection of inelastic strain
zones in mine workings and control over hazardous plastic strain zones
at Antei deposit.
For safety of mining and reduced risk of
production suspension, work areas at Antei deposit are equipped with
DIAMEC-232 core drilling rig for non-productive drilling and rock stress
state assessment using core disking method.
The application of the
rock pressure control system with the option of data transmission and
live browsing on a PC allows advanced forecasting of rockburst hazard
and finding of areas in rocks that need destressing and occupational
safety enforcement.

CHARACTERISTICS OF THE ACTIVE FAULT STRUCTURES ACCORDING GEOELECTRICS CONTROLLED SOURCE
Methods
geoelectrics controlled source (transient electromagnetic sounding,
vertical electrical sounding, electrical resistivity tomography) are
used for monitoring the electrical parameters of the geological massif,
under the influence of natural and anthropogenic geodynamic processes.
The main goal of such work is the prediction of natural hazards,
landslides, rock bursts, suffoziozno-subsidence processes in the mining,
quarrying, located in seismic areas, or exposed to strong anthropogenic
influences. The fault fractured zone, available in sediments and
geological foundation of the array may be seismogenerating, so the
definition of their activities is an important task.
For data
analysis, electromagnetic monitoring of the electrical parameters
considered two – electrical resistivity and coefficient of electrical
anisotropy. Estimates of variations of these parameters and their
comparison with the intensity of the elements of fault tectonics makes
it possible to assess the degree of fault activity revealed violations.
Using the two parameters increases the information content of the study.
Key words: non-stationary
electromagnetic sounding, vertical electric sounding, electrical
resistivity to-mography, electromagnetic monitoring, variations of the
electrical resistance, the coefficient of electrical anisotropy,
activity of fault disorders.

UNIFIED APPROACH TO MODELLING AND CONTROL OF TECHNOLOGICAL TRANSPORT
Possibilities
of different approaches to transportation systems modelling are
analyzed. The main topic of the paper is the problem of general
representation of technological transport motion within a spatially
distributed industrial and/or logistic object. The general model of such
transportation process is developed in the form of a hybrid system (an
event-switched process), i.e., a system with qualitative and quantative
dynamics which state changes on switching hypersurfaces. The model is a
set of relationships of the following types:
1) ordinary
differential equations representing continuous dynamics of active
elements while the qualitative state does not change; 2) condition of
switching, i.e., qualitative changes of the process in question; 3)
formulas of state transformations due to switching events; 4)
constraints on controls, pertaining both to stages between switching
events and to switching events. Elements of the general model are
exemplified with representation of dynamics and control choice for
transportation units and loaded or unloaded stores (concentrators).
Different
ways of description and choice of controls are presented, namely as
given control laws that may express different algorithms of operative
dispatch, interactive control choice and solution of local optimum
control problems. Possibilities of the model use for current prognosis
and operative control as well as organisation of simulation aimed at
substantiation of both control system and th
