Research on Analysis of Security of Mining in Yaoqiao Coal Mining under Weishan Lake
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.
