【摘要】 根据兖州矿务局南屯矿3303观测站在开采33上03-1工作面时的实测资料，本文提出了回采过程中地表卢、的移动特征和地表点的移动参数相对于工作面主断面的分布规律；并在此基础上提出了采动过程中地表点在任一方向上的移动变形公式；其次提出了地表点最大下沉速度分布的表达式等。更多还原

【Abstract】 Based on data actually observed at the No. 3303 surface station at Nantun Coal Mine,Yanzhou Mining Administration, the paper sheds light on the characteristics of movement of surface points during mining and based on which the formula for calculating their deformation in arbitrary directions and maximum settling rates are presented.更多还原
