The exploration areas of Guogou mine was 15.32 km2.The water inflow was 34.07m3/h and less than 10-30 times as opposed to near mining area. On the basis of regional hydrogeological condition, hydrogeological condition and water filling factors of Guogou exploration areas, investigation was made to composition, source, and reasons of smallscale for near mining area of water inflow. Normal water inflow and hydrological exploration type of Guogou exploration areas were definite. The analysis on hydrogeological conditions has the guiding and reference significance to design and development of mine, mine safety production and the near mining area hydrogeological work.% 郭沟煤矿勘探区面积15.32km2，涌水量34.07m3/h，与周边面积接近的矿区相比，涌水量小了10-30倍，文章研究了郭沟勘探区区域水文地质条件、勘探区水文地质条件以及勘探区充水因素，分析了勘探区涌水量的组成、来源以及比周边煤田小的原因，确定了勘探区正常涌水量和水文地质勘查类型。勘探区水文地质条件的研究对未来矿山设计、开发、煤矿安全生产以及相邻矿区水文地质工作具有指导和借鉴意义。
