Actuality of problem. For last ten years the water resources of Donetsk coal-basin have undergone significant changes of negative character, in view of influence on them of the enterprises coal industry, metallurgical, coking chemical and power industry. During the given period of time the small rivers of region have changed basic geomorphological and also landscape and geochemical parameters. Inflow in a hydrographic network of waste mine waters (volume about 800 million a cube ìeters of the year) has resulted in increase of a parameter of salinity of natural waters from 2,3 up to 2,9 gramme on the litre, that is confirmed by complex researches, which were spent both on regional, and at state levels. In the countries of Europe the daily average consumption of water (on the city dweller) makes 100-200 litres, in Ukraine - 320 litres. Together with it in Donetsk coal-basin there is a deficiency of water in volume more than 27 litres on the man. Working on today water supplys structures constructed 40-30 years back, are not capable to maintain needs for water both in quantitative, and in qualitative aspect. Stoppages of water supply and the often failures of water and sewer networks push to a complex solution of a considered problem. Became obvious, that in investigated region it is necessary to address to use of alternative sources of water supply - waste mine waters, volume of which education allows, at performance of the certain technological operations on their preparation, to rank them as resources, which in a consequence can be used for industrial water supply of region. One of the main limiting factors of use of waste mine waters in industrial water supply is their high demineralization. Therefore it is necessary to develop the appropriate theoretical base, on the basis of which the creation (and improvement) and practical application of the certain technologies sweeting-out of water which is taking into account concrete conditions of manufacture and object in views is possible.

The purpose of work is the comparative estimation of existing methods and choice of the most perspective industrial ways of demineralization of salty waters and mining on this basis of rational technologies sweeting-out of waste water for the enterprises of a mining industry on an example of coal mines of Donetsk and Ìàêåyåvêa area.

The practical importance of work. The basic technological circuit swweeting-out of mine waters which is offered in view of a composition of waters and state of existing refining structures can be recommended for an intrusion on as at the base enterprise, and on other coal mines of Donetsk coal-basin.

Scientific results and their novelty

1. Is proved perspectiv of demineralization of mine waters on the basis of application of methods opposite îñìîñà, that essentially reduces power expenses on sweeting-out of mine waters.

2. The basic laws of change of a quantitative and qualitative composition of mine waters Donetsk and Ìàêåyåvka area are analysed, that has allowed to apply the most efficient technological circuit of process of demineralization of mine waters.

3. Is proved and the technological circuit of setting sweeting-out of mine waters is developed on the basis of a method reverse osmosis, which will allow to ensure water of drinking quality from waste mine waters the rent enterprise "Mine by À.F.Zasijadêî".

4. The recommendations and offers for an intrusion demineralizations technologies on mines of Donetsk coal-basin are developed.

Methods of researches. In this work are used the analysis and generalization of advanced achievement of a science and engineering on a construed problem, analysis of the design documentation on existing and designed sweeting-out to settings, method of the engineering analysis of design solutions, the technical and economic final pays and economic-mathematical is simulated, and also collecting of experimental data on natural and mine waters for Donetsk and Ìàêåyåvka area. The processing of the received data is conducted on personal computer with engaging of methods of mathematical statistics.

Object of research is industrial technologies of demineralization of mine waters.

Approbation of master qualifying work. The separate sections of master work were reported and were debated on XXIV of a scientific and technical conference of the students (DSACE, Ìàêåyåvêà, Donetsk state, 27 - April 28, 1999); on III All ukrainian of a scientific student's conference "Ecological problems of regions" (ÎGÌI, Odessa, 25 - April 26, 2001); on Ist of the International scientific conference of the students and post-graduate students "Protection of an environment and rational use of natural resources" (DNTU, Donetsk city, April 16-18, 2002).
