本文主要介绍了地质勘探和采矿设计中几种主要图件（诸如柱状图、剖面图、平面图等）的数据存贮与处理方法，其中包括岩性花纹符号，各种构造，地物等特殊线条，光滑曲线及文字标注的处理，这些技术均含在目前开发的煤矿地质计算机辅助设计（ＭＧＣＡＤ）中，它使编辑后的图形数据可被直接利用，且保留了图形数据库中的地质含义，减少了编辑量，集成了运行环境，方便用户掌握与使用。 This paper mainly introduces the data storage and processing methods of several main map (such as histogram, section, plan) in geological prospecting and mining design, including special lines such as lithology pattern symbols, various structures and objects Smooth curves, and text annotations, all of which are included in the currently developed Coal Mine Geology Computer-Aided Design (MGCAD) which allows the edited graphical data to be utilized directly and preserves the geological implications of the graphical database and reduces The amount of editing, integrated operating environment, user-friendly and use.
