摘    要:通过含水层地质特征、构造控水作用及水平水化学特征等因素分析,进行鱼田堡矿区水文地质特征研究,探讨水文地质条件对煤层气成藏的控制作用。鱼田堡矿区构造复杂,深部煤层采动裂隙发育程度渐高,长兴组灰岩含水层与其他含水层水力联系增强,不利于煤层气的富集成藏,浅部煤系含水层出露带煤层气含量低于矿井北部深水平未出露地区。随着开采水平的深入,水化学环境的脱碳酸作用和矿化度程度渐高,煤层气的赋存条件变好。

关 键 词:构造控水  水文地质特征  水化学环境  煤层气赋存

Abstract:This paper takes a detailed discussion on the hydrogeological characteristics in Yutianbao mining area,respectively from the aquifer geologic characteristics, tectonic - controlled water and hydro - geochemical character-istic in different mine levels, studies methane enrichment controlled by Hydro -geological conditions in the area.Research shows that the regional complicated structure, developing roof breakage. It is enhanced that the hydrody-namic relation between the aquifer of limestone of Taiyuan and other aquifers, against methane reservoir formation.Gas content in exposure belt of the shallow aquifer in coal bearing series is below deep levels at north - unexposedarea. In addition, this paper points out that underground water chemical environment of de - carbonation and de-gree of mineralization is high along with the depth of the coal seam .
Keywords:tectonic - controlled water  hydro - geological conditions  water chemical environment  reservoir ofcoal bed methane
