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 ,得出了厚松散层下开采的地表移动参数与松散层厚度的定量关系以及地表移动期的量化特征
According to the measured data of the Yongxia mining area in the east of Henan Province, the characteristics of surface movement induced by mining under the thick and loose layer are analyzed. The discrimination method of the surface mining stability and the dual media model are expounded. The quantitative relationship between the movement parameters and the thickness of the loose layer and the quantitative characteristics of the surface movement period
