ON POSSIBILITY OF NEW SINK HOLES IN THE FLOODED MINE BEREZNIKI 1
Four
sink holes occurred in potash mines of «Uralkali» OJSC: one in
Berezniki3 and three in Berezniki1. Estimated maximum volume of cavern
in salt rocks in Berezniki3 mine is 1.1 thous./m
3, in Berezniki1 mine (sink hole № 3) – 515 thous./m
3.
Shape of the caverns and sink holes– irregularly truncated cones.
Diameters of smaller cone bases are 32–60 m. Sink holes in Berezniki3
and № 1 in Berezniki1 arose due to flooding the mine, and sink holes № 2
and № 3 in Berezniki1 arose 2–3years after full flood of the mine.
The
article presents an analysis of two versions for arising the sink holes
№ 2 and № 3. According to one of them the sink holes arose due to MgCl2
leaching from fallen layers into carnallite seams strata, thickness of
which accounts for 30–35m. By leaching voids are formed, volume of which
makes up to about 43% of ore.
Estimation of voids volume balance,
which except for leaching voids include chambers volume in sink hole
contour and volume of salt solution by flooding, has shown that this
volume is much less than the volume of insoluble rocks of the sink hole
and the volume of the fallen salts. It follows that by leaching MgCl2 of
carnallite only downfold formation is possible.
The second version
consists in that except for carnallite leaching during the mine flood in
the area of the sink holes № 1 and № 3 discontinuity of water proof
formation occurred, and flowing fresh water solved rock salt. Analysis
of mining and technical conditions and estimations of pillar and cap
pillar stability have shown that discontinuity occurred. Estimations of
salt solubility and fresh water flow have confirmed that it is quite
enough time for inflow of necessary volume of fresh water and salt
solution in the period since discontinuity of water proof formation till
the mine flood.
By the study results it has been specified that the
sink holes caused by MgCl2 leaching are not expected in the sites of the
flooded mine Berezniki1 where fast subsidence is observable. Although
final subsidence can exceed 14metres.
Key words: sink hole, cavern, solution, leaching, salt rocks, insoluble, mine flooding, pillar sta
bility, roof stability.

EXPERIMENT OF LONGHOLE STOPING OF THIN URANIUM ORE DEPOSIT
Nowadays
in OJSC “PIMCU” due to mining of rich ore resources in a comfortable
mining-and-geological and mine-technical conditions the share of ore
breaking from thin ledge with low uranium content increases together
with the depth of mining activity. To maintain the overall ore
production the enterprise has to increase ore output what will cause the
increase finance and physical resources at this technology. This makes
it necessary to find new ways of uranium breaking from poor and
off-balanced ores.
Such ores can be economically reasonable broken
with the use of physical-chemical geotechnology of block-situ leaching
of uranium.
One of the main factors determining the efficiency of
block- situ leaching is a designated size of crushed pieces of a
product, what is achieved by using sustainable data of drilling and
blasting works.
This article contains the results of performance
evaluation of blasting works of existing enterprise technology of
longhole stoping and size of broken ore. Weighted size of a piece,
oversize yield and coarseness of grading are used as an evaluation
criteria. We made a conclusion about inexpedient use of existing
technology of longhole stoping at ore preparing for block situ leaching.
Key words: uranium

source of hydrogen used to simulate the formation of methane in coal.
Iron compounds were identified by Mössbauer spectroscopy. Using electron
paramagnetic resonance is established that both compounds increase the
concentration of electronic spins in graphite, i.e. contribute to the
formation of dangling bonds on carbon atoms. However, the influence of
siderite is significantly higher. Method ion mass spectrometry measured
methane at low temperature heating of mixtures and found that the
presence of iron compounds intensifies the formation of methane in coal
and ferrous iron is a more effective catalyst for this process.

INFORMATION
SUPPORT FOR THE ESTABLISHMENT OF NETWORK MODEL OF ENTERPRISES OF THE
MINING INDUSTRY FOR EXAMPLE INFORMATION-ANALYTICAL SYSTEM BANKING AND
FINANCE
For the analysis and forecasting of the State enterprises
of the mining industry to develop network models, which are
simultaneously processes flows of products, and the structure of the
link functional sub-systems. This approach led to the establishment of
information-analytical system of banking and finance, which for more
than 15 years, provides a monthly update of information, in the form of
products in paper and electronic version for clients working with the
banking system of Russia. The information system is the basis of
reporting banks, the knowledge base is a network model Bank, which shows
cycles of flows of funds input and output tools hosted cycles. Based on
the Information-analytical system Banking and Finance we calculate 170
indicators created dynamic rating of financial stability, condition
index of the Russian banking system. Users of the system are the Central
Bank of the Russian Federation, VEB, Gazprombank, HSE and other
organizations.

DEVELOPMENT OF RESOURCE-SAVING TECHNOLOGIES BASED ON ADEQUATE DATA ON CONTENT OF NATURAL SULFIDES IN TECHNOGENIC DEPOSITS
Integrated
waste management development sulfide deposits include the use of acid
mine water with high concentrations of metals for the preparation of
leaching solutions. Quality «liquid ores» significantly increased,
reduced acid consumption. Increased filtering ability dumps results in
an increased rate of oxidation of the minerals and increase the
concentration of various metal sulphates in a productive solution.

METHODOLOGIES
OF RESEARCH OF A MASSIF AT DESIGN, CONSTRUCTION AND OPERATION OF
UNDERGROUND CONSTRUCTIONS FOR THE PURPOSE OF THE ACCOUNTING OF POSSIBLE
RISKS AT AN ASSESSMENT OF EFFICIENCY OF PROJECTS OF DEVELOPMENT OF A
SUBSOIL THE GRADOPROMYSHLENNYKH OF AGGLOMERATIONS
The principles
of methodology of research of a massif and design of underground objects
in the gradopromyshlennykh agglomerations based on the theory of design
of complex development of a subsoil stated in M.I. Agoshkov, K.N.
Trubetskoy, N.V. Melnikov's works are created. Approaches to
economic-mathematical modeling of design decisions are considered. The
main types of risks and the reasons of instability of a massif at
development of a subsoil of megalopolises are revealed. Methods of an
assessment of the specified types of risks which are based on
theoretical fundamentals of probability theory and mathematical
statistics, the expert analysis are considered. It is revealed that the
perspective direction of forecasting of technological risk is
application of the theory of adaptation of difficult technological
systems. Conclusions are presented that at design, creation and
operation of geotechnological system which structural elements are
underground con-structions in the urbanized territories, it is possible
to use and apply the theory and appendices of indistinct sets as they
provide the forecast of behavior of elements of geotechnological system,
both at stochastic, and at linguistic uncertainty.
Key words: gradopromyshlenny

ASSESSMENT
OF THE ECONOMIC LOSSES ASSOCIATED WITH THE CONDITION OF THE INJURY AND
WORKING CONDITIONS AT THE ENTERPRISES OF MINING COAL, BROWN COAL AND
PEAT IN THE RUSSIAN FEDERATION
Evaluation of economic costs and
losses in the mining of coal, brown coal and peat associated with
providing compensation to employees engaged in work with harmful and
(or) dangerous working conditions and industrial injuries and their
possible reduction as a result of changes in the labour legislation of
the Russian Federation in connection with adoption of the Federal law
“On special assessment of working conditions” is presented.
The
largest share of the economic costs and losses before 2014 accounted for
the costs due to lost working time associated with unfavorable working
conditions and injuries. In this kind of economic activity it was about
11% of added cost of manufactured products and services. These losses
can be reduced by a factor two as a result of the reduction in the
number of employees who will be provided compensation for work in
harmful and (or) dangerous working conditions, as well as possible
decrease in the compensation.
Key words: employment injuries,
harmful and (or) dangerous working conditions, compensation, special
assessment of working conditions, economic losses, fund of working time,
extra leave, reduced working time.
