山西昊兴塬煤矿瓦斯赋存规律研究

On Gas Occurrence Regularities in the Haoxingyuan Coal Mine, Shanxi

研究区位于山西著名的霍西煤田中西部区域,区域含煤地层出露稳定,潜在资源量巨大。研究表明:井田含煤地层主要为上石炭统太原组(C_(3)t)和下石炭统山西组(P_(1)s),可采煤层主要为9、10和11号煤层;煤田地质构造复杂程度属于简单型,褶皱、断层和陷落柱等对煤层影响较小;研究区的矿井瓦斯主要受煤层埋深与上覆基岩厚度的影响,而受其他因素影响不明显。

The research area is located in the central-western part of the famous Huoxi coalfield of Shanxi Province.The study shows that the coal-bearing strata in the mine field are mainly Upper Carboniferous Taiyuan Formation(C_(3) t)and Lower Carboniferous Shanxi Formation(P_(1)s),and the available coal seams are mainly No.9,10 and 11 coal seams.The complexity of geological structure of the coal field belongs to simple type.Fold,fault and collapse column have little influence on coal seam.The coal mine gas in the research area is mainly affected by the depth of coal seam and the thickness of overlying bedrock.
