摘　　要：以Knothe模型的函数为基础,对不同推进速度下动态地表移动和变形进行了研究,结果证明,提高开采速度有利于减小地表采动损害。Base the functions of Knothe model, the paper studied the dynamic surface ground displacement and deformation under different mining speeds. The results showed that the increased mining speed would be favorable to reduce the mining disaster to the surface ground.
