摘　　要：针对深部开采地表沉陷预测与控制问题,以铁法矿区大强矿为例,通过资料分析了深部开采地表沉陷规律;采用数值模拟方法,分析了深部开采地表移动机理。研究表明,深部极不充分开采,地表下沉值和下沉速率均较小,地表下沉活跃期不明显。深部开采表现为地表一定范围内的整体下沉,影响范围扩大,地表下沉系数相应减小。采用概率积分法进行开采沉陷预计时,应对地表移动参数进行修订。In order to solve the problems of surface subsidence predicting and controlling under deep mining, it taking Tiefa coal min-eas an example, surface subsidence rules of deep mining were analyzed, surface movement mechanism of deep mining was analyzed bynumerical simulation.The results showed that surface subsidence value and subsidence rate were all small, when mining was ex-tremely inadequate in deep, surface subsidence active period was unobvious.The characters of deep mining were special scope of sur-face subsidence entirely, influence scope expanded and surface subsidence coefficient decreased.Surface movement parameters should be revised when probability integral method was used in mining subsidence predicting.
