STUDY AND CRITERIA DEVELOPMENT FOR THE EFFICIENT PRODUCTION OF THE ELECTRIC POWER AT THE HYDROELECTRIC POWER STATION AND SYSTEM ANALYSIS OF ITS CONSUMPTION AT THE ENTERPRISES OF NON-FERROUS METALLURGY

Klyuev R.V.

The paper presents the results of the energy audit at the industrial en­terprises of non-ferrous metallurgy - The Open Joint Stock Companies "Pobedit" and "Electrozink". Special attention is paid to the study of the electricity quality, mainly non-sine voltage. On the basis of techno-eco-nomic analysis of electrical equipment of the SES companies it was re­vealed that the expected economic effect from reducing the level of the higher harmonic components (WG) would be about 7.5 million rubles.

INVESTIGATION OF MASS HARDENING PROPERTIES OF LAYING IN THE PREPARATION OF FILLING BLEND COMBINED TECHNOLOGIES

Gabarayev O.Z., Lolayev A.B., Khulelidze K.K., Bitarov V.N.

The research results of the artificial massif properties from the solid stowing the underground mining are listed. It is established that the placement unstable compounds in the goaf under gravity flow leads to their layering into several zones. It has been revealed that the activated stowing has a more uniform distribution of filler during the mixture motion in the mechanical activator at 1,0-1,5 m/sec, resulting in the increased hydration of binding materials 2-3 times and the mixture strength by 20-25%.

RESEARCHING AND CALCULATION OF THE TAILING DAM STABILITY DURING THE ANTHROPOGENIC DEPOSIT OPERATION

Lolaev A.B., Akopov A.P., Oganesian A.Kh., Sumin M.N.

A complex of numerical methods was used for predicting the stability of the tailing dam in Norilsk industrial region (Northern. Siberia). The carried out calculations include the calculation of the temperature conditions for the tailing dam on the basis of UWay FEM package, the calculation of the tailing dam stability on the basis of UniFos FEM package. The forecast of the geoecological processes on the basis of the described methods will allow to increase reliability of the accepted design decisions.

STANDARDIZATION CONCEPTUAL BASES OF POLLUTANTS EMITTED BY MOTOR VEHICLES

Badalyan L.K., Kurdjukov V.N., Aleynikova A.M.

In this paper the lacks of the environmental orientation of the pollutants emitted by motor vehicles standards are considered. The analysis of a single automobile and a transport stream emissions depending on the movement speed performed by the authors allows to draw the following conclusions. First, the microimpurity mass expense represents the ekologo-economic indices for an estimation of the valid level of the negative influence on environment from the mobile sources gases. Secondly, the ecological integrated index of harmful substances emission is recommended with aimed at the vehicle drivers observance the economical responsibility for the urban ecosystem pollution.
