摘　　要：为解决水体下安全采煤,保护地表水以及水库坝体安全的技术难题,采用UDEC数值模拟的方法对申家庄煤矿扩大区在岳城水库下采煤的安全性进行了研究。根据模拟结果分析,"两带"发育最大高度为96 m,波及含水层,但均为弱富含水层,在以后开采过程中需提前探放水;导水裂隙带未与水库底部接触,故水库对采煤工作面不构成威胁。In order to solve the technical problems of safe coal mining under water,protect surface water and reservoir dam safety,the safety of coal mining under the Yuecheng reservoir in the extended area of Shenjiazhuang coal mine was studied by UDEC numerical simulation.According to the analysis of the simulation results,the development of ＂two belts＂ maximum height of 96 m,and the aquifer,but are weak rich water,after the mining process is required to discharge water;water flowing fractured zone and the bottom of the reservoir,so the reservoir of coal face no threat.
