中文摘要：

衡量矿山地下开采引起地表移动的变形参量包括下沉、水平移动、倾斜、水平变形和曲率,根据其具有显著的空间特征,首次提出了山区采动地表数字地面模型种类,并应用山区开采沉陷预计绘制了地表移动变形等值线,结合矿区地表建筑物损坏的临界变形值,提出应用数字化形式对地表建筑物损坏等级及损坏范围的判定方法,以此为矿区地面建筑物的预先防护提供决策。

英文摘要：

The deformation parhmeters to evaluate the surface movement caused by underground minin.g include subsidence, hor- izontal movement, tilt, horizontal deformation and curvature. According to the obvious spatial characteristics, the types of dig- ital terrain model of mining surface in mountain area were firstly proposed. And the mining subsidence prediction was used to draw contour lines of surface movement and deformation. Combined with the critical deformation value of surface building dam- age in mining area, the way was proposed that used the digital form to judge the damage grade and range of surface building, so as to provide decision for the previous protecxion of surface building in mine area.
