Composition of soil air and microflora in different soil horizons (to 30 cm depth) over some closed Donbas coal mines has been studied. The intensive methane leakages have been found in some soil zones over the closed coal mines. This results in formation of explosive and inflammable gas mixtures. Methane content in soil gas mixtures could vary from trace amounts to 34 %. The essential decrease of oxygen (to 3-4%) and increasing (up to 5 %) of CO2 concentrations that evidences for active microbiological processes in such soils is marked in the latter case. Methanotrophic bacteria involving methane into biogenic cycle are widespread (up to 106 cells per 1 g) in methane-containing soils over the closed coal mines. Microorganisms of different physiological groups in the community with methanotrophic bacteria were found in the given technogenic econiche.
对顿巴斯一些封闭煤矿上方不同土壤层（至30厘米深度）的土壤空气和微生物群落组成进行了研究。在封闭煤矿上方的一些土壤区域发现了强烈的甲烷泄漏。这导致形成爆炸性和易燃性气体混合物。土壤气体混合物中的甲烷含量可从痕量到34%不等。在后一种情况下，氧气显著减少（至3 - 4%），二氧化碳浓度增加（高达5%），这表明此类土壤中存在活跃的微生物过程。在封闭煤矿上方含甲烷的土壤中，参与甲烷生物循环的甲烷营养细菌广泛存在（每1克土壤中多达106个细胞）。在这种人为生态环境中，发现了与甲烷营养细菌群落中不同生理组的微生物。
