| 摘 要： | 结合我国煤矿瓦斯H2S异常矿井的地质构造、水文条件、H2S体积分数、煤类、煤自燃状况，研究煤矿瓦斯H2S异常矿井的地域特征和层域特征。结果表明，H2S异常区主要分布于新疆维吾尔自治区、山西省、四川省等省区；H2S异常煤层主要分布于石炭纪、二叠纪和侏罗纪等煤层中。H2S异常区具有良好盖层，地下水与其他含水层水力联系弱，煤级为焦煤及以上，为硫酸盐热化学反应成因。该研究为煤矿瓦斯H2S异常区预测与治理提供了参考。

| Abstract: | Based on the geological structure of H2S abnormal mine in coal mine methane, hydrologi- cal condition, H2S volume fraction, coal types and coal spontaneous combustion condition, this paper is a study of regional characteristics and layer domain characteristics of H2S abnormal mine in coal mine methane. The results show that H2S abnormal areas are usually distributed in Xinjiang Autonomous Re- gion, Shanxi Province and Sichuan Province and the H2S abnormal coal seams are mainly found in coal seams of Carboniferous Period, Permian Period and Jurassic Period. H2S abnormal areas have favorable overlying strata, weak hydraulic connections between the underground water and other aquifers, and coal rank above coking coal, the factor of sulphate thermal chemical reaction. This research would provide ref- erences for prediction and management in H2S abnormal areas of coal mine methane. |
