摘　　要：根据豫东永夏矿区的实测资料 ,分析了巨厚松散层下开采引起的地表移动特征 ,阐述了地表采动稳定的判别方法及预计的双重介质模型 。Based on measured data of Yongxia Mine field, author analyzed surface movement character caused by mining under very thick loose overburden, expatiated judge method of surface stabilization after mining and double mediums model to forecast, concluded the quantitative relation between parameters of surface movement and the thickness of the loose overburden and quantitative character of surface movement's time These has some important value to academic study of surface movement caused by mining under very thick loose overburden and actual production

关 键 词：巨厚松散层 采动程度 地表移动参数 双重介质模型 覆岩 下沉系数
