摘　　要：为了研究在采动条件下,黄土沟壑地形对地表移动变形的影响,以神东矿区大柳塔矿52304工作面为例,布设了地表移动观测站,研究了黄土沟壑地形条件下地表移动变形规律。对观测成果研究分析发现,受采动影响,沟壑两侧的松散层向沟壑滑移,地表移动变形规律表现出特殊性,具体表现为:沟壑两侧观测站产生了一个向沟壑方向的水平移动分量,最大为0.398m;滑移产生了一个垂直移动分量,使沟壑底部下沉小两侧下沉大,最大垂直移动分量为0.809m;垂直滑移分量与水平滑移分量的比值P与地形坡度i之间存在一定的线性相关。In order to research the influence of loess gully terrain on surface movement and distortion under mining condition , taking 52304 mining face of Daliuta Colliery as an example , surface movement observation station was set up.Observation result showed that influenced by mining , loose bed at two sides of gully slid to gully and surface movement rule took on particularity.The horizontal move-ment component was largest 0.398 m and vertical movement component induced by slide was largest 0.809 m.Ratio of vertical slide component to horizontal slide component p was linear dependence with surface gradient i .
