| 摘 要： | 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。 |
| 关 键 词： | 水体下采煤 区域关键隔水层 导水裂缝带 |

| Abstract: | 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. |
| Keywords: | mining under water body regional key aquifuge water flowing fractured zone |
