摘    要：矿山地表移动带的固定是地下矿山规划与设计中的一项重要工作，而变传统的手工绘图为计算机CAD辅助绘图则能快速准确地完成这项任务结合矿山地表移动带的确定原理，以CAD软件为基本工具，提出了一种基于岩体移动角的矿山地表移动带计算机辅助生成法，并研究确定了该方法的具体操作方法①直接在地质剖面图中根据岩体移动角绘制移动边界线，与地表交点即为该方向矿山地表移动带外边界点；②或者先在地质剖面图中确定矿体最深(或最突出)部位的X(或Y)及Z坐标，将该点投影到地表地形图中，通过计算机辅助绘图得到该方向的地表移动带外边界点；③将所获得的地表移动带外边界点依次连接形成闭合曲线，得到矿山地表移动带该方法在某矿山地表移动带的固定中获得了成功应用，效果良好。

Abstract:

Based on the basic principles of determining mine surface movement scope by rock movement angle, an auto-generating method using CAD was proposed, with the following steps:find out the intersection points of the ground surface with the mine movement boundary according to rock movement angles in the geological sectional drawing; determine firstly the coordinates of the deepest point (or the most prominent point) X (or Y) and Z in the selected geological sectional drawing, then to project that point to the surface topographic drawing, furthermore the mine movement scope boundary point is determined through mathematic drawing method on considering the contour line and the profile intersect at one point; the mine movement scope is finally formed by connecting all the boundary points together.
