摘　　要：以河南郭沟煤矿大倾角逆断层正上方1000k V晋东南-南阳-荆门特高压线路为研究对象,采用数值模拟方法,对逆断层两侧煤层开采特高压线塔变形规律与岩层移动特征进行了研究。得出了逆断层上、下盘煤层不同开采顺序与塔基斜率和塔基中心下沉值的变化关系,揭示了上、下盘岩层的移动特征。研究结果可为类似条件下高压线塔下采煤提供参考。The 1000kV ultra- high voltage transmission is on the reverse fault with large inclination in Henan province as the research object. Numerical simulation was used to study the tower deformation rules and strata movement characteristics due to two sides mining of reverse fault. The relationship between different mining sequences of hanging wall and footwall of fault and the tower slope and center subsidence was obtained. The characteristics of strata movement were revealed. The research results could provide reference for coal mining under high voltage transmission towers in similar geology condition.
