The hydrogeological conditions of the Kuznetsk Coal Basin (Kuzbass) region are considered. Estimates of the safe yield and natural groundwater resources for this region are given. Better-quality groundwater are shown to be available for public water supply to some localities in Kuzbass. The applicability of mathematical modeling to forecasting the changes in the hydrogeological conditions caused by flooding of unprofitable mines is discussed.  相似文献

Palynological complexes of deep-sea sediments, which formed under changing climatic and hydrological conditions of the Late Quaternary sea basins and adjacent land, are studied. It is shown that alternating phases of climate aridization and humidification have caused the appearance of peculiar associations of spores, pollen, and microfossils, as well as characteristic lithological indications in bottom sediments.  相似文献
