煤层开采对岳城水库安全运行的影响

Impact of coal mining on safety of reservoir

本文综合现场工程地质调查结果、室内岩石力学试验、现场测试、矿井涌水量统计、水质分析、理论计算以及数值模拟结果,得出了申家庄煤矿在岳城水库库区水体下采煤引起的地表塌陷范围不会波及到大坝安全,煤层开采也不会造成岳城水库库区水体发生渗漏,从而造成水库水位骤降,库区渗流场不会发生大的改变。研究结果论证了申家庄煤矿在岳城水库库区下采煤是可行的。

The Shenjiazhuang Coal Mine is located at the north bank of the Yuecheng Reservoir. The investigation on engineering geology, test on mechanical properties of rock, measurement of leakage water in mining tunnel, test of leakage water quality and numerical simulation are carried out to study the probable impact of mining on the safety of the reservoir. It is concluded that the minor subsidence taken place at the bottom of the reservoir will not seriously affect the operation of the reservoir. No serious leakage will occur. The mining beneath the reservoir will not affect the safety of the reservoir.
