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.

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%.

The paper presents a mathematical model of information retrieval subsystem based on fuzzy sets, which takes into account the associative relationship and the context of the terms in the document search pattern. The proposed mathematical model of the document search pattern car. be used in solving the problems of classification, clustering, searching for similar documents in ERP-system's data collection.

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.

At the flotation process example the calculation method of the admissible errors for the processes parameters from the mode ones and the control affects values determinations in the technological map frames were described.

The methodic and research results of lead and zinc extraction from Mizur ore dressing plant tails and Arkhonsky mine ore using the agitation leaching proceeded by disintegration in DEZ-11 are described. The analyses of the results the regression equation could help to determine the most effective leaching models and the independent factors influence level.

The mountain areas of the North Caucasus possesses a huge energy potential. Its use will allow to increase the reliability of power supply systems, considerably as well as to reduce the consumed of the electric power cost for consumers.
