摘要
采用常规的圈定地下开采岩石移动界线和FLAC数值模拟两种方法,分析了小王庄铁矿地下开采对大秦铁路的影响,得出了小王庄铁矿地下开采引起的地面沉降对大秦铁路的影响甚微的结论,为小王庄铁矿后续生产提供了有力的科学依据。
The influences of underground mining in Xiaowangzhuang Iron Mine on Daqin railway were analyzed by the general delineating removal line of mined rock and FLAC numerical simulation. It is concluded that the underground mining in Xiaowangzhuang Iron Mine had little influence of surface subsidence on Daqin railway, which provide effective scientific basis for following - up production of the Iron Mine.
