摘要： 勘探工程的布置是多种多样的，在见矿的勘探工程和未见矿勘探工程之间，必然存在一个矿体尖灭位置。研究了矿体尖灭构建中的平均尖灭角法、有限推断法和无限外推法算法，并利用.NET语言，结合Object ARX 2007 完成了矿体尖灭自动生成系统，该系统运行稳定、操作简单、生成的尖灭线合理、直观、易于用来形成实体模型。

关键词: 尖灭线构建系统, 有限推断法, 无限推断法, 平均尖灭角

Abstract: Though the layouts of exploration engineering are variable, there must be a site where an orebody vanishes between the exploration engineering that finds the ore and that which finds no ore. The algorithms of average pinchout angle, finite distance extrapolation and infinite distance are studied and used in constructing orebody pinchout lines. The orebody pinchout auto creation system is realized by using NET language and Object ARX 2007. The system runs stably and is easy to operate. It can produce reasonable and visualized pinchout lines, facilitating the formation of solid model.

Key words: Pinchout line constructing system, Finite distance extrapolation, Infinite distance extrapolation, Average pinchout angle
