本文结合大屯矿区姚桥煤矿现场地质资料、实测资料，按照水体下采煤的技术理论，对微山湖下第四系松散层结构和隔水性、覆岩破坏规律进行了分析研究，进而对姚桥煤矿微山湖下采煤的安全性进行了分析论证。得出3隔和4隔为区域关键隔水层，能够有效防止湖水溃入井下；导水裂缝带发育的最大标高达不到基岩顶部，波及不到关键隔水层，无法导通湖水结论。

This paper combined mining in Yaoqiao Coal field geological data and the measured data, according to the theory and technology of the coal mining under water body , analyzes the structure of Quaternary Loose Soils and the overburden failure law , and also predicts the ground surface deformation, and then analyzes and proves the security of Yaoqiao mine coal mining under Weishan Lake. Draw 3 compartment and 4 compartment for regional key aquifuge and it can effectively prevent the lake water burst into the underground . The maximum elevation of development of water-flowing fractured zone can' t reach the top of the bedrock, and can' t spread to the key water- resisting layer , and can' t form the crack of conducting the lake.
