| 摘 要： | 胡襄矿区是河南省新发现的大型煤炭后备开发基地.经勘查,地面下960～1400 m为二叠系下统山西组煤系(二煤组)地层,含中厚—厚煤层2层,属中高变质的贫煤、瘦煤及焦煤.由于该区煤岩层埋藏深,封闭性较好,瓦斯逸散条件差,致二煤层赋存有大量的瓦斯,且全区富集.本文就胡襄矿区深部煤层瓦斯的赋存及其地质特征进行了剖析,为以后进...

| Abstract: | The Huxiang coalfield is a newly found large coal reserves base in Henan Province.Exploration reveals that,the coal measure strata of Lower Permian Shanxi formation(the second coal formation) occur in 960 to 1400 m below the surface,with two layers of medium to thick coal seams,belonging to peranthracite,lean coal and coke.Because the coal beds in the area are deeply buried,and well closed,a large number of gas is preserved in the coal seam and enriched in the whole area.The analysis on the geological features of deep coal seam and gas occurrence in the Huxiang coalfield will provide basic information for further study on the accumulation conditions and occurrence of gas. |
