摘　　要：介绍了露采矿山整治中山体坡面表面积的两种计算方法:剖面法和小三角锁法。剖面法是把宕口坡表面分割成无数个小梯形进行计算表面积的一种方法。小三角锁法是通过对宕口坡表面数字化测量,根据测量数据建立数字高程模型,并在表面建立小三角锁,对所有小三角的面积累加得到面积的一种方法。小三角锁法大大提高了计算的准确度和效率。Two types of computation methods about surface area for the open pit mines are presented in the text. They are section method and triangular mesh method. Section method is to split the pit slope surface into several trapezoids so as to calculate their surface area; through a digital survey of the pit slope surface, a numerical elevation model is set up, on the surface the triangular mesh is built, and all the triangular meshes are piled up to get the surface area.
