The methods of research are statistical analysis, generalization and systematization of the real material on hydrogeological conditions of the coal mining and working influence on the geological environment. The estimation for the ecological-hydrogeological conditions is obtaind as draining and contamination of aquifers, violation of the river network, river water pollution and salanitization as a result of mine water discharge, day surface subsidence above working area ,flooding and underflooding, soil bog formation. The preliminary estimate of the water balance state change in the region has been given, the main sources of working flooding and their in different regions and conditions provision with water resources has been defined. Forecast of geological environmen t changes under the influence of the coal field abandon hes been drawn up, propozals of nature protection character have been prepared. The fild of application - mining art, coal industry, environment protection, hydrogeology. Product Description popup.authors popup.nrat_date 2020-04-03 Close
