摘　　要：近松散层水体条件下,煤层开采过程中出现的溃水溃砂问题,是煤矿开采过程中的主要矿井工程地质灾害问题之一。研究了工作面水文地质结构、覆岩工程地质类型与结构,采用经验方法和数值分析,计算了覆岩垮落带和导水裂缝带的发育,并结合以往预防溃水溃砂的研究成果,分析了33下01辅助工作面发生溃水溃砂灾害的可能性。并提出预留煤柱的具体方案。There were often water bursting and sand bursting accidents occurring in coal mining near loose water body,which was one of the main geologic disasters of mine engineering in coal mining.Hydrogeologic framework of working face,geologic type and structure of overburden engineering were studied.Development of overburden caving zone and water flowing fractured zone was calculated by the empirical method and numerical analysis.In the light of the previous achievements of anti-water bursting and anti-sand bursting,the possibility of water bursting and sand bursting occurring in the 33low 01 auxiliary working face was analyzed.The actual scheme to pre-retain pillars was advanced.

关 键 词：水体下开采 溃砂 导水裂缝带 松散层
