摘　　要：在进行矿山开采沉陷预计时,常常将预计点设计成格网状,从而预计结果数据呈现出特殊性。文中基于矩形格网状开采沉陷预计数据,结合移动变形等值线绘制要求,研究了一种便于实现的等值线生成算法,并采用VC++6.0开发平台编程实现。研究表明:该算法原理简单,易于编程实现,满足工程需要。During prediction of mining subsidence,the surface points were usually designed as grids.Therefore,the data of prediction results were special.In this paper,based on the grid mining subsidence prediction data and combining with the drawing requirements of the moving deformation isoline,an algorithm of isoline generation was studied which was easy to implement based on VC++6.0.Research showed that the method was simple and fast in calculation,and easy for realization.It could be used for other similar types of data,and met the needs of the project well.
