Ecological and economic problems of mine waters for Donbass are one of most acute.

     On the one hand, mines of Donbass (is more exact, Donetsk and Lugansk oblast) eject in hydrosphere up to 700 million m3 of mine waters per one year, i.e. about 10 m3 on 1 ton of the extracted coal. Unfortunately, it strong-saline waters (basically, sulphate-chloride) - on the average concentration of salts 2-5 г/л, and in some cases - up to 20 г/л. Ejection of such supersalted waters renders sharply negative influence on a condition of reservoirs of Donbass, as huge volumes of this dump (700 million m3/ year) are comparable to volumes of a natural drain of all rivers of Donbass (on the average 600 million m3/ year). It is no wonder, that the majority of the rivers of Donbass concerns to categories ”dirty” and “very dirty”.

     Thus it is necessary to note, that closing of mines does not influence in any way reduction of volume of dump of mine waters - they are necessary for pumping out from the closed mines as a minimum in former volumes. Moreover, last decade the disturbing tendency of increase of a mineralization of mine waters is traced. Also it is important to note, that in in one their projects of closing of mines questions of complex use ejected mine waters practically were not considered and were not solved.

     On the other hand, the Donetsk area concerns to regions with sharp deficiency of water both technical, and municipal. Even in conditions of slump in production (in comparison with 1990) this deficiency makes on area about 500 million m3/ year.

      At last, from the third party, the iron and steel industry of Donetsk area is the largest consumer of water resources - 250-300 million m3 / year of technical fresh water (except for a plant “Azovstal” which uses sea water directly from sea of Azov).

      Therefore the idea of use of mine waters (after their conditioning) for needs of an iron and steel industry is rather attractive, since will allow to solve both ecological, and economic problems of neutralization and recycling of mine waters. I.e. the question is that on each of seven metal works of Donbass were _caieioou_ mine waters of one - two nearby mines.

      For example, mine waters of recently closed mine _”Red October”_ (about 500 m3/ hour or about 4,5 million m3/ year) may be used for technical water supply Enakievsky Metal Work (ЕМW).

1. To show real ways of the decision of ecological and economic problems of recycling of the salted mine waters of Donbass.
2. To begin uses of mine waters for needs of all metal works of Donbass.

1. All necessary documentary and technological acknowledgement of a reality of use of mine waters for technical water supply of metal works will be received.
2. Dump of harmful mine waters in reservoirs of Donbass decreases.
3. The fence of extremely scarce of technical and drinking water by metal works decreases.
4. There is a prospect of supply by potable water of depressive mine settlements after closing non-rrofitable mines.
5. Are created in this settlement some of new workplaces (on installation of conditioning of mine water).

      Necessary investments:

1. 1500 000 grivna on the equipment and installation;
2. 200 000 grivna/year on operation of a complex;
3. 100 000 - contingencies.
4. Total - for first two years - 2 000 000 grivna = 320 000 EUR.
5. Time of realization - 18 months;
6. Time of recovery of outlay - 3 years.
