摘　　要：通过对芨芨湖西井田地质特征、煤层、聚煤规律等进行综合分析研究,西山窑组在成煤期,历经多次湖进湖退,长期处于浅湖和沼泽交替环境,形成煤层层数多、厚度不均、有分叉合并特点。结合西山窑组水文地质条件、工程地质条件、环境地质条件及其他开采技术条件研究,表明研究区水文地质条件简单;工程地质条件差,具有岩体完整性为中等完整—完整性差—岩体破碎,煤层顶底板岩石稳固性差的特征;环境地质条件中等,煤层瓦斯含量低,具有爆炸性,易燃等。该研究为研究区进一步开发建设提供借鉴意义。Through the comprehensive analysis and research on the geological characteristics, coal seam and coal accumulation law of Jijihu West Minefield, it was concluded that Xishanyao Formation experienced many times of lake into and retreat during the coal-forming period, and it was in the alternating environment of shallow lake and swamp for a long time, forming the characteristics of many coal layers, uneven thickness and bifurcation merger. Combined with the hydrogeological conditions, engineering geological conditions, environmental geological conditions and other mining technical conditions of Xishanyao Formation, it was showed that the hydrogeological conditions were simple;the engineering geological conditions were poor in the study area, with the characteristics of medium integrity-poor integrity-broken rock mass and poor stability of coal seam roof and floor rock. Environmental geological conditions were medium, coal seam gas content was low, explosive, flammable and so on. The study provided reference for the further development and construction in the study area.
