New principles of ground waters exploitation reserves assessment metodology in relation to the areas of their intensive exploitation

The article covers the topical issues of discrepancy in expected and actual condition of the areas of intensive ground waters exploitation. The issues are caused by the significant excess of reserves being on government accounting over allowed and actual water intake. The offers of new assessment principles of ground waters exploitation reserves in such conditions were developed, based on study analysis and the usage of ground waters in Moscow region. The main idea is that all reserves of subsurface resources open acreage should be considered as offbalance reserves. The actual and permitted, according to production licenses, water intake should be taken into account when calculating interactive water intakes. It was offered to perform drawdown calculation from the interactive water intakes by extrapolation of ground waters extrapolation data for longstanding period of time. Key words: ground waters exploitation reserves, subsurface reserves open acreage, balance and off-balance reserves, permitted water intake, monitoring.

Geological risks, their estimation and optimization in course of ground water deposits modeling

The article provides the survey of the main factors determining the natural and anthropogenic geological risks, emerging during estimation of ground water reserves. The main ways of risks’ estimation and optimization in the course of ground water reserves estimation by numerical modeling method are listed in the article. It is pointed out that one of the most significant objective risk factors is the lack of hydrogeological information or its incompleteness. This kind of risk estimation and optimization should be performed on the basis of factor and range evaluations of models’ parameters in course of geological exploration works as well as at the stage of expected values calculations when designing water intakes. Key words: risks, water intake, ground water, geological exploration works, design, possibility, hydrogeological model, numerical modeling.

Standard and substandard drinking and waste ground waters The issues of study, purpose of usage, regulatory system

The article covers the issues of substandard ground waters usage for drinking. Owing to the progress achieved in water treatment sphere, and particularly owing to reverse osmosis application, almost all natural ground waters (except salt brines) may be treated up to the quality required for drinking water supply. The problem of accumulating residual solution disposal is solved by its reinjection into the deeper levels. The article contains recommendations on regulatory system improvement; the recommendations are based on the critical analysis of the existing regulatory system, which restricts the notion «drinking ground waters» and their study, as well as waste water discharge into resources. Key words: drinking and waste ground waters, regulatory documents, drinking water supply, degrees of quality, water treatment, discharge into resources.

Geofiltrational model and assessment of stocks Verkhnemzymtinsky of the field in conditions Intensive anthropogenous influence

The article describes the formation of operating reserves of Verhnemzymtinsky deposit located in the upper part of river Mzymta valley, the Black Sea coast, Caucasus. The main source of reserves formation is the river Mzymta’s surfacewater flow. In previous years, the value of resource base depended on underflow deposits exploitative colmatation applied to the newly explored deposits, the exploitation of which based on the hydro-geological analogy method. The intensive construction in the river’s valley, which has started in 2010, resulted in the significant increase of river-water sediment load. The river-water sediment load continued increasing during the whole year which resulted in the progressive underflow deposits colmatation and in decrease of ground water deposits volume. These values were calculated using modeling method. Key words: commercial reserves, Verhnemzymtinsky deposit, surfacewater flow, underflow deposits colmatation, modeling method.

Induced polarization processes study for geocryological tasks solution

The phenomena of fast-going induced polarization of permafrost rocks and its effects during operation with inductive (NFTES method) and galvanic (VES-IP method) facilities. By the example of Chayadinsky deposit operation, favourable and non-favourable situations for determining (using NFTES method) polarization information concerning permafrost state of cross-section rocks are described. Two polarization processes, which differ in nature and characteristics, are found out for VES-IP galvanic facility. They are slow electrokinetic IP and fast-going IP related to rock mass’s permafrost state. The article contains the results of researches at permafrost rocks, which determined the interrelation of IP parameners and cryo-parameters.

Peculiarities of the ground water reserves re-estimation being influenced by group water intake

The article represents the working results related to re-estimation of deposits of Zapadniy water intake owned by «Krasnodarneftegas » Ltd. Water intake is located at the end of large Troitsky water intake owned by Troitsky Fresh Ground Water Basin, Krasnodarsky region. Ground water intake of Zapadniy water intake is small. It cannot be the key factor in the Troitsky FGWB area and it does not influence on hydrodynamical situation in the area. Over decade, annually Troitsky water intake has been using only 52 % of deposits estimated in 1979. The significant water intake enlargement is not expected. As the resources of Zapadniy water intake were estimated on the basis of Troitsky maximum load, it resulted in the significant changes in the way of its operation and it also resulted in the additional well drilling. Key words: fresh ground water resources, hydrodynamic conditions, a numerical model, prediction tasks, migration tasks.

Hydrogeological conditions analysis for contact-karst gold field associated with the problem of explored deposits underflooding

Gold field is located in the Asian part of Russia, in the nearsurface area of platform cover over the prominent crystallic basement. Common geological conditions, expected in the course of exploration and mostly confirmed during the mining in open-cut way, became more complicated in some areas of ore field because of underflooding and the decrease of working levels grounds’ bearing capacity. It causes the mining works stopping. On the basis of factual material analysis and field studies, the reasons of these developments are defined and the measures concerning hydrogeological researches are recommended. This is aimed at optimization of pit protection system from water irrigation. Key words: gold field, merzlotno-hydrogeological conditions, lateral stream, irrigation of career developments, engineering and hydrogeological researches, intra planimetric drainage system.
