ON POSSIBILITY OF NEW SINK HOLES IN THE FLOODED MINE BEREZNIKI 1
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./m3
, in Berezniki1 mine (sink hole № 3) – 515 thous./m3
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.
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.

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.

GEODYNAMICS OF THE MOSCOW METROPOLITAN AREA AND RADIATION HAZARD-BASED TERRITORIAL RANKING
area of the city of Moscow is analyzed in terms of radiation along one
of the faults running southeast northwestward. Based on the data of the
analysis of the gross contamination factor W for the Moscow city
sectors, the urban areas are ranked. The ranking can be used as a
reference criterion in determining sequence of radiation–ecology surveys
in civic and apartment buildings in Moscow in the framework of annual
geodynamics, radiation safety, gamma rays, isotopes of radon.

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.

(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.
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.

DETERMINING TRENDS OF DEVELOPMENT AND ACTIVITY FOR ALMAZNAYA MINE
this article the analysis of the world market of coal from 2001 to 2012
is carried out. Coal mining volumes in Russia are analysed in the
underground and open way. The group of the mines extracting anthracite
is carried out. Tendencies of development of activity of “Almaznaya”
mine are considered. The most influential indicators are defined by the
powered by correlation analysis. Are defined by the regression analysis

MANAGEMENT OF MINING PRODUCTION OF RUSSIAN ARCTIC: PROBLEMS AND SOLUTIONS
main problems of management of mining companies in the Russian Arctic.
The directions of the state policy on development of deposits of natural
resources in the Russian Arctic territories and the implementation of
innovative projects, including the Arctic shelf. Designated Western
countries imposed sanctions against Russia and assessed their impact on
Arctic mining companies. Examples of import-substitution policy,
creating conditions for the development of and demand for innovative
technologies, increase economic growth in the Arctic. The problems of
governance in the field of environmental protection of the Arctic.
Examples of measures to reduce emissions into the environment, which are
held major Arctic mining production companies. The analysis of the
opportunities for training and retraining of personnel in educational
institutions of higher education for the mining enterprises of the
Russian Arctic. It was determined that the training and development of
personnel create and implement well as large corporations, businesses
which operate in the Russian Arctic. Examples of training, retraining
and advanced training of executives and specialists in mining
enterprises in the Arctic. The necessity of legal regulation to attract
