Development’s conditions and sources of microorganisms in high-grade iron ore (HGIO) of Jakovlevsky deposit (KMA) were considered. Influence of watering, draining and contamina tion in iron ore on decreasing of shear strength and growth of bacterial mass were noticed. Dif ferent physiological groups and species composition of microorganisms in underground space were defined, and their influences on constructional materials which are used to coffer mine workings were studied.

The purpose spent monitoring is resulted. The comparative analysis of results of three cycles of a hydro-geological monitoring which has shown gradual expansion of front of an over flowing of underground waters from not-drained horizon is made. Negative consequences of such process are specified. The development features of various biological forms of a life in mine which destroy construction materials are noted.

- V. P. Skobelina
- I. S. Tremasova
Transition of the Russian economy from export-raw to innovative development is possible on the basis of a diversification and increase of corporations innovative activity by carrying out cluster policy. In article distinctive features of industrial and cluster policy are analysed, theoretical aspects of industrial cluster creation are considered. Also the system approach to formation of innovative-industrial clusters of mineral-raw specialization is presented, the basic measures of a complex estimation of the cluster group importance are allocated.

The analysis of the current state and ways to improve the effectiveness of the Russian mineral resource base reproduction
- Authors:
- V. S. Khloponina
Economic stability and competitiveness of the Russian Federation in many respects depends on a condition of the mineral resource complex process of reproduction of which demands constant state control and regulation. Mining gain is provided by geological prospecting and exploration. The insufficient volume of the assignments in exploration negatively affects on efficiency functioning of many industries and national economy as a whole. For this reason the problem of geological prospecting and exploration demands special attention and the prime decision. In the article the analysis of a current state of mineral resource base of the Russian Federation is carried out, the basic problems of prospecting branch are designated, ways of attraction of investments to mineral resource sector are defined.

Way remote magnitometrichesky control of the technical condition of the main pipelines
- Authors:
- A. N. Lyubchik
Last decades maintenance of reliability of objects of oil and gas has considerably become aggravated. It is connected with considerable ageing of pipelines which almost on 45 their % them are maintained more than 20 years, and 20 % – over 30 years, besides poor quality of designing and building in a combination to the limited service life applied film insulating materials of pipes lead to appreciable decrease in an operational resource. Thus, the urgency of maintenance of reliable, accident-free and effective work of pipeline system became obvious. In offered work application remote magnetometric the control, on the basis of application magnetometric equipments is described.
