摘　　要：在预测显德汪矿区小构造区域的基础上,结合现场已经揭露的小构造的类型,建立具有相同应力异常区的数值模型。对开采工作面前方顶板、底板的采动应力场进行数值模拟。采动应力使采矿工作面前方的断层活化,容易导致突水,研究其演化过程及规律可以为煤矿的安全生产提供参考。Based on the prediction of small mining structures in Xiandewang mine and combined with the exposed small structure types on site,simulated models with same abnormal stress areas were established.The mining stress fields of the roof and floor in front of the mining face were numerically simulated.Due to the mining stress would cause fault activation in front of the mining face and lead to water inrush,studies on its evolution and laws can provide a reference for the safe production of coal mines.
