Geochemical properties of water under the waste heaps in Chervonohrad mining region

Abstract

The geochemical properties of water under the waste heaps within the Chervonohrad mining region have been studied. The environmental remediation around the technogenic reservoirs of rock heaps using the bioplateau systems is proposed. In 2017, samples were taken from reservoirs of technogenic origin located at the foot of rock heaps of such coal mines as “Mezhyrichanska”, “Velykomostivska”, “Stepova”, “Zarichna”, “Lisova” and “Chervonohradska”. According to the analysis of the studied parameters, it has been determined that water under the Mezhyrichanska Mine waste heaps is the most polluted. The most dangerous landscape-transforming factor of water under the waste heaps is the transfer of polluting substances into the soil, surface and subterranean waters. Through the use of the Pearson coefficients of correlation, the ratios between pollution patameters have been obtained. The determined correlation coefficients are high, positive (r = 0.78 – 0.99) and evidence of the toxic components spread in water under the waste heaps throughout the entire coal mining region. The obtained geochemical data on water under the waste heaps of mines in the Chervonohrad mining region are important in terms of the environmental impact assessment of mining activity on the human body and the biosphere components – the hydrosphere, the phytogenic field. It is necessary to establish environmental monitoring systems and to develop measures for the environmentally safe decommissioning the waste heaps of coal mines.
