“…The studies were done in 2010-2013. Soil samples were taken from genetic horizons on catena: nominal standard brown soil (upper part); technogenic alkalinized, contaminated gleysolic brown soil [3] (middle part); waste coal materials -litostrats [4]; hemo-techno-dark humus-gleysolic soil (lower part). Mine water samples were taken in middle and lower part of catena.…”

Waste coal impact degree on chemical composition of soil solutions were studied by key hydrochemical parameters in the industrial area of abandoned Avangard coal mine. It was found that the impact of waste coal and mine waters is seen in accumulation of sulfides and silicon compounds in humus soil horizons; iron, chrome and copper in mineral horizons. Close correlation between chemical composition of mine waters and composition of soil solution was found.

Theoretical issues of joint underground storage of hydrogen with methane are poorly studied, and practical examples are rare. Therefore, it is extremely important to analyze the mutual influence of hydrogen-methane mixtures and the host geological environment. This article presents material that makes it possible to substantiate the most significant hydrochemical processes that affect the transformation of cap rocks. For this purpose, the results of our own experiments, as well as published data on the study of the influence of hydrochemical conditions on the diffusion loss of hydrogen, its interaction with rock-forming minerals, organic matter, and pore waters were used. A quantitative assessment of the decrease in the moisture saturation of clay-rocks samples and, as a consequence, the loss of the mass content of mineral and organic substances is given. It was found that the cyclic change of thermobaric effects leads to a change in the redox conditions in the system “rock ↔ pore water” and is accompanied by an increase in the reactivity of calcium, magnesium, sulfur, iron. The saturation indices of pore water with carbonate and sulfate calcium salts were calculated under the conditions of their precipitation, dissolution, and removal from solution. The interpretation of the experimental data made it possible to substantiate the most probable transformations in clayey cap rocks, which affect their screening capabilities. It is recommended to take into account, when designing and operating storage facilities for hydrogen-methane mixtures, the variety of accompanying hydrochemical and microbiological processes that affect the change in the filtration properties of cap rocks.
