On the basis of theory of physical and chemical hydrodynamics of porous environments the mathematical model of migratory processes is offered in underwaters, adjoining to the pond of territories. On the first stage of researches a hydrodynamic net is built. The planned task by quantitative prognosis estimation of contamination of underwaters as a result of lauter losses of pond decides the system of unidimensional equalizations on the ribbons of current. The cascade method of reconstruction of pond is offered, fully eliminating contamination of aquiferous horizons. Key words: hydrodynamic net, contamination, aquiferous horizon, migratory process.

The estimation of a degree of toxicity of products of thermal processing of waste before and after detoxification is lead. The comparative analysis sorption properties of natural materials concerning toxicity of waste is executed. It is established, that for detoxification it is possible to use clay and loams of the certain mineral composition. Key words: waste, detoxication, neutralization,natural sorbent.

Researches of the contents of water-soluble forms of heavy metals in different types of dumping mine rocks of the Western Donbass are executed. According to existing state sanitary rules and norms two methods calculate indexes of toxicity for lead, cadmium, zinc, cobalt, nickel, copper. The estimation of an opportunity of application of existing norms and rules at definition of a class of danger of firm waste of the coal-mining industry. Key words:heavy metals,waste,toxicityrock.

Processes of transfer of thermal energy are widespread in the nature and cover all complex of the phenomena of carry of heat in space that is caused by a difference of temperatures of separate elements of system. They are connected with the various physical phenomena existing in geotechnical systems of any level, and demand detailed studying. Keywords: thermal energy, geotechnical system, a heat transfer, convection.
