摘　　要：结合司马矿首采面的地质情况,分析了充水水源,探索了薄基岩区充水通道和工作面排水条件,预测了首采面的涌水情况,给出了防治水工作建议,得出来首采工作面薄基岩区水量不大是由于基岩水本身很小和表土层底部没有含水层,风化带水得不到补给的结论。According to the geological situation of Sima mine＇s first mining face, the study analyzes the water-filling source, explores water-filling channel of thin bedrock areas and drainage condition, predicates the water flow, and provides the water-prevention suggestion. Then the reasons of short water volume are concluded as follows： water is shortage in bedrocks, there is no aquifer under the topsoil and water cannot be recharged in weathering zone.

关 键 词：充水水源 含水层 涌水量 薄基岩
