摘　　要：为研究薄基岩、近距离煤层煤矿防治水的规律,以凉水井煤矿为例,在结合现场相关资料的基础上,通过经验公式计算、FLAC3D数值模拟、相似材料试验等方法,总结得出顶板裂隙多数发育至松散层甚至地表,且上组煤与下组煤裂隙导通,这与现场勘查结果相符。针对矿井防治水问题,提出了采前疏放与采后疏排相结合、留设防水防沙煤岩柱、引流工程与地表裂缝回填相结合的技术方案。In order to find out the rule of thin bedrock and prevention and control, conclusion has been summed up that even the earth＇s surface and the fracture of upper group coal consistent with the result of field inspection, giving example close distance coal seam mine＇s water most roof fracture extend to loose layer and lower group coal connect which is of Liangshuijing coal mine, based on combing related field material, through methods of calculating on empirical formula, FLAG3D numerical simulation, similar material test and so on. Aiming at problems of mine prevention and cure water, technology project of combing dredging forward and rock pillar, combing drainage project with backfilling afterwards, setting waterproof and sand-proof coal the earth＇s surface fracture has been put forward.
