The article analyzes the ecoforming factors during the ore extraction in the North Caucasus. The harmful affect of the mining- processing production on the environment, the geomaterials extraction processes influence on the landscape deformation was shown. The results of the harmful affect on the region biosphere were pointed out as well. Simultaneously the method of the harmful affect minimization on the ecosphere is presented.
The chemical compound of the rivers in Southern Kyrgyzstan is substantially formed under the influence of natural factors, and also under the influence of pollution produced by the unorganized sewage of cities and settlements. In article the territory entering into of the river pool of Syr-Darya is considered, the hydrochemical characteristic of the large rivers constituted the pool is given.
Basins of the Western Ciscaucasian rivers are located in the Kubano-PriAzov lowland and cover the territory stretching from the Don And Manych river valleys in the north and north-east to the Kuban River in the south. Rivers receive water due to melting waters, rainfalls and ground water. Snowmelt is the key source for replenishment. It amounts to 70-74%. Flooding due to increase of ground water level resulted from the large number of ponds and nearby are located in Krasnodar reservoir. Flooding makes it impossible to use lands for agriculture. In 2005 1100 thousand hectares of lands were flooded.
A new approach for the solution of different control problems transforming them into multi-criteria ranking problems based on comparison standards and intervals between these standards and corresponding large scale systems is proposed.
During winter fields expeditions 2000-2010 in Elbrus region seasonally freezing and main cryogenic processes in highland were studied. We detected, some cold winter thickness of active layer (seasonally freezing layer) can amount 1,5 m. Interaction between seasonally freezing, snowdepthand altitudewas studied. For example, on the south are slope of Elbrus by bellow below altitude of2450 m and at a thickness of snow more than 1 m the seasonally freezing wasn't observed. In addition, main cryogenic processes of Elbrus region were studied.
The research results of the stressed mine mass under worked with the rich ore mining are presented and the technological decisions providing the effective ore mass state control during the former under worked ores treatment involvement are suggested.
The new data concerning the magneto liquid separation process based on the ponder motor impact of the separation magnetized medium (ferromagnetic liquid) on the inside nonmagnetic bodies were obtained. The FML behavior in the vibration field was theoretically studied and dependence of the absorbed energy value on the vibration amplitude and frequency was revealed.
In the article the function chart of condenser installation of indemnification of jet capacity is considered at asymmetrical loading. On the basis of the scheme the mathematical model of a measuring part of the device of indemnification of jet capacity is developed.
To develop the technology of the gold bearing ores enrichment at the native deposit, the gold extraction factory with productivity 10 t/h was designed and built. The factory is founded to test new grinding schemes, gravitational flotation enrichment, hydrometallurgy, the discharge disposal and the rejects stocking. The article gives a scheme of the factory equipment chain, describes the equipment use and presents the results of the Nagalkinsy deposit industrial ore tests.
The principal causes influencing stability of ledges at processing of the Bosnian open-cast mine in a hilly terrain are considered. For the first time borders of action of gravitatsionno-technical pressure on a bottom and ledge boards are established. The technique of statement of ledges in limiting position with application of the planimetric crack formed both dynamic, and static influence is offered.
