摘要
基于煤田地质勘探资料,分析了寿阳—阳泉煤矿区主力煤层含气量的区域分布规律和中奥陶统灰 岩、太原组灰岩和山西组砂岩的地下水动力场、水化学场特征,探讨了煤层含气量与地下水水位或矿化度之间的耦 合关系,得出了地下水滞流地区,矿化度高、煤层含气量高的结论。
In the paper, the regional distribution laws of coalbed methane content in the main coal beds at Shouyang—Yangquan coal mine district and the characterisics of the hydrodynamic fields and hydrochemical fields of the formation water in Middle Ordovician limestones, Taiyuan Formation limestones and Shanxi Formation sandstones were analyzed on the basis of the data on coalfield geological exploration; the coupling relation between coalbed methane content and formation water potential or salinity is discussed; and it is concluded that the formation water at stagnant area is of the characteristics of high salinity and high coalbed methane content.
