Title: Distribution of Heavy Metals in the Coal Mine Waste Dumps Based on Statistical Analysis Authors: POPOVYCH, VASYL; MENSHYKOVA, OLGA; VOLOSHCHYSHYN, ANDRIY; GENYK, YAROSLAV; PETLOVANYI, МYKHAYLO; ILKIV, BOGDAN Abstract: At the UN Climate Change Conference in Glasgow in autumn 2021 (COP26), world leaders and participants decided to phase out coal energy and gradually replace fossil fuels. At COP26, Ukraine has committed to shutting down state-owned coal-fired power plants by 2035, reducing methane emissions by 30% by 2030 and halting deforestation. The waste dumps are also a detrimental factor in coal mining. The determination of the heavy metals content in the waste dumps of coal mines is a topical issue today, as the results of such studies are part of the monitoring of the environmental safety of mining regions. This scientific article considers the results of research on the heavy metals content in the waste dumps and their distribution in one of the largest coal mines in the Lviv-Volyn coal basin –‘Chervonohradska’ (Ukraine). 2.9 million m3 of rock have accumulated in the dump since 1971. Every year, 40,000 m3 of fresh rock is dumped. Samples were taken uniformly from all sides of the dump in places with no vegetation cover. Note that exceeding the maximum allowable concentrations of the studied heavy metals is observed in all areas except for Zn. Statistical analysis of the results of semi-quantitative spectral studies of waste dumps rockat the Chervonohradska mine site was performed using the Statistica 8 applied statistics package. According to the results of more than 50 samples taken at a depth of 0.3 m, the statistical distribution of heavy metals Mn, Pb, Ni, Cu, Zn and Co in the mine dumps was determined, and a correlation analysis was performed. It was found that the distributions of Cu and Zn in dumps are closest to normal. The nonparametric Spearman coefficient (rs) revealed the average level of correlation of the content of heavymetals in the pairs Mn and Ni (rs = 0.46), Mn and Zn (rs = 0.52), Ni and Zn (rs = 0.57), Cu and Zn (rs = 0.49). Chaotic and uneven discharge of rock onto the open area caused uneven substrate deposition of certain chemical elements in the profile of the dump.

Title: Екологічний стан природно-технічних геосистем ліквідованих шахт Львівсько-Волинського вугільного басейну EcoLab. Том 3 Authors: Волощишин, Андрій Ігорович; Попович, Василь Васильович; Босак, Павло Володимирович Abstract: Монографія присвячена вивченню особливостям впливу чинників еколого-техногенної небезпеки ліквідованих шахт на підсистему природних об’єктів (ґрунти, поверхневі та підземні водойми, повітря, біота) та ренатуралізації підсистеми штучних об’єктів (девастовані ландшафти) за допомогою фітомеліоративних методів. Результати досліджень температурних та вологісних режимів згасаючих териконів у весняний період показали, що найбільшими температурними режимами характеризувалися ділянки у місцях горіння, які розташовані на поверхні середнього ярусу південної експозиції схилу. Встановлено, що вміст важких металів у породі неоднорідний. За середнім значенням, перевищення ГДК виявлено для Pb, Ni та Co (шахта «Червоноградська»).

Title: Monitoring of Heavy Metals Migration intoEdaphic Horizons of Coal Mine Dumps Authors: Попович, Василь Васильович; Волощишин, Андрій Ігорович; Тиндик, Олег Стефанович; Меньшикова, Ольга Володимирівна; Шуплат, Тарас Ігорович; Босак, Павло Володимирович Abstract: Mining of minerals is accompanied by direct irreversible changes in the biosphere. An analysis of the latest researches on the technogenic hazard of rock dumps at coal mines, as well as specifics of their reclamation and phytomelioration in a global context, necessiates the study of the ecological state and natural phytomelioration of the Nadiya mine waste heap in the Lviv-Volyn coal basin (Ukraine). This scientific work presents the results of research on heavy metals migration into the genetic horizons of the rock dump, as well as their influence on forming the phytomeliorative cover on its surface. It has been revealed that the studied site of the No.4 rock dump in the 0-15 cm horizon, which is located from the eastern side near the foot, is the most contaminated with heavy metals. The indicators of heavy metal content at the background site, which is located within a radius of 3 km from the rock dump, are the lowest in the 0-15 cm horizon. The uneven distribution of heavy metals in the genetic horizons of the rock dump substrate is caused by frequent landslides, changing rock acidity, heterogeneity of natural overgrowth, and existing combustion sources. In the event of precipitation, toxic compounds, heavy metals and other harmful substances are washed out from the rock dump surface, and in our case, these substances also enter the natural water body.
