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./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.
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.

sink hole, cavern, solution, leaching, salt rocks, insoluble, mine flooding, pillar stability, 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.

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:
