Okhotnyk K. Ecological optimization of the system of mine waters releases in a river network (on the example of the Samara river basin)

The thesis is devoted to new ecological system of optimization of mineralised mine waters influence on ecological safety of river basin territory. Generals of method: creation of the specialized base of the indexes of source of danger and natural waterflow (as an expense and mineralization of natural waterflow for to the periods, mine waters mineralization level of coal mining enterprises etc.), determination of coefficients of the natural leveling of danger, substination of regional mineralization critical level. The critical values of mineralisation are determined – 3.0 gpl – on the base of this parameter grounds furter calculations of river water quality. The realization of this method of regulation of mine waters releses on the basis of balance model assumes redistribution of mine waters volumes according to the natural waterfalls assimilating ability. Regulation will be more effective when deal with the whole river basin – it’s improve decline of natural waters mineralisation on 20,2%.
