General varieties and peculiarities of structures formation associated with processes of tectonomagmaticactivization are examined. Known types of molybdenum and tungsten mineralization, with localized at ancient cratons are characterized. Attention to positive perspectives of the Ukrainian Shield activized zones is paid. Key words: tectonomagmatic activization, molybdenum and tungsten mineralization.

The different methods of determination of gold are considered in geologica objects. Description of the most complete extraction of noble metals is resulted from a hinge-plate. The terms of atomic-absorbing determination of gold are optimized in a water and organic phase in air-acetylene flame and with the use of electro-thermal sprayer.

The mathematical model changes hydrogeological conditions of the territory in the zone of tailings «Balka Stukanova».It is based on the hydrodynamic grid and contains 2 parts – filtration and migration. Estimated filtration tasks solved method by the double superposition. Migration processes are investigated based on the theory of physicochemical hydrodynamics of porous medias. Research results should be used for scientific study of environmental activities hydrogeological direction. Keywords:mathematical model, filtration, mass transfer, hydrodispersion, migration,tailing, groundwater, prognosis.

The multivariate mathematical models of the recultivated, recultivated and dumping with dry system, recultivated in systematically irrigation conditions and free of overgrowth by wild plants are proposed, designed and quantified. The theory of physico-chemical hydrodynamics of pore space using analytical and numerical methods for solving the equations of motion and mass conservation of matter all models are based on. The adequacy of built models and man-maid processes that proceed inside the mine dumps is proved. Key words: mathematical models, recultivation, mass transfer, adequacy.

The movement of water and salts in zone of aeration under irrigated conditions is described by the equations of motion and mass conservation of the material. Salt transport processes forecast calculations are performed for the scientific rationale of environmental measures complex. The reliability of the result depends on the applied methods of calculation. A comparative analysis is made for analytical solution of the classical mesh scheme in the explicit and implicit variants and Johnson's method. Key words: zone of aeration, moisture transfer, mass transfer, hydrodispersion, forecast.

Researches of the contents soluble forms of heavy metals in waste are executed. The estimation of a degree of toxicity of products of thermal processing of waste is lead. It is established, that slag of an incinerate factory concerns to І class of danger under the contents of mobile forms of heavy metals. Key words:heavy metals,waste,toxicity.

In research of geotechnical systems and revealing of ways of possible management of them, studying the dynamic processes occurring as in the system, and the surrounding geological environment, is one of the basic directions. Authors have considered possible ways of studying of thermal and gaz-hydrodynamic modes of geotechnical systems which the thermal field of underground burning of coal influences. Key words: thermal energy, geotechnical system, a heat transfer, convection.
