摘　　要：以Knothe模型的函数为基础,对不同推进速度和不同时间影响系数下动态地表移动和变形进行研究。结果证明:提高开采速度有利于减小地表采动损害;时间影响系数c较小时,下沉迟缓,最大动态变形值较小,随着c的增大,地表动态变形值增大。Based on the Knothe time function,the paper introduces the law of progressive movement and deformation is given under different mining speed and different time influence factor. The results show that the rapid mining method would be an effective help to reduing the mining damage in practice and that maximum deformation indices will decrease with the decrease of the fluence factor, c.
