摘　　要：为解放浅埋煤层受上覆含水层及地表河流等水体威胁煤炭资源,以沁水煤田平定昔阳矿区运裕井田为试验区,通过覆岩破坏规律的研究,以及防水安全煤岩柱、防砂安全煤岩柱及安全采厚计算,对不同控水采煤方案对比分析,开展了浅埋煤层水体下控水采煤防治水技术研究。结论表明:运裕井田15#煤层回采后顶板覆岩裂采比为18、冒采比为11,限厚开采是一种有效的控水采煤方案。To exploit the coal resources of shallow coal seam threatened by overlying aquifer and rivers, taking Yunyu well field in Pingdingxiyang Mining Area of Qinshui Coalfield as the experimental area, the different water-controlled coal mining methods were compared and analyzed through studying overburden rock failure laws, calculating waterproof safety coal pillar, sand-proof safety coal pillar and safety mining thickness, and the water-controlled coal mining technology for water body under shallow coal seam is developed. The results show that： the fractured zone-mining thickness ratio is 18, the caving zone-mining thickness ratio is 11 after coal mining in Yunyu well field 15#coal seam; the limited thickness extraction is an effective method for water-controlled mining.
