中文摘要：

鉴于某矿区地表移动观测站的非正规布置,根据观测线上三个临界变形值位置,确定地表影响椭圆分布区域的边界点；建立独立坐标系,将边界点与坐标原点进行联合观测,计算出边界点相对于原点的坐标值,然后将各个坐标值代入椭圆方程,求取地表影响椭圆半轴长,根据移动角与开采边界的空间几何关系,计算出矿区的岩层移动角.研究表明,该方法简洁实用,能够满足开采沉陷工程的实际要求.

英文摘要：

Given a mine surface actual layout of the movement observation station, according to the position of three critical deformation value in the observed line, the boundary points of surface elliptical distribution zone are determined; an independent coordinate system is established, the boundary point with the coordinate origin is jointly observed, coordinate values of the boundary point relative to the coordinate origin are calculated, then put each coordinate values into elliptic equat!ons, strike the length of surface elliptical axle, according to the spatial relation between the movement angle and the boundary geometry to calculate the strata movement angle. The research shows that this method is simple and practical, which can meet the actual requirements of mining subsidence engineering.
