【摘要】 地质柱状图与矿层对比图在地质图件中是十分重要的两个图件，它们在矿山生产活动中应用广泛，也是定量解决各种地质问题的基本依据和先决条件。地质柱状图按其应用分为钻孔柱状图和地层综合柱状图，它们的绘制方法大致相同。矿层对比图是以柱状图数据为基础绘制的图件，其标志层连线主要为突出标志层信息。 本文从面向生产实际应用的角度分析钻孔数据资料的特点，概括图件绘制类型，建立数据模型结构，总结自动生成图件的知识体系，阐述自动绘制地质柱状图与矿层对比图的基本原理，对数据组织结构、柱状内部符号设计、填充方法以及文本自动换行方法进行了描述，提出一种基于分段思想的缓冲线绘制算法。对对比剖面图的自动绘制方法做了说明。并以此为基础，利用面向对象的程序设计方法，从底层开发出了柱状图与对比图自动绘制系统，此系统提供了与其太原理工大学硕士研究生学位论文它地理信息软件交换数据的接口，达到了数据共享的目的。并且成功地应用到实际工作中。更多还原

【Abstract】 Geology columnar section and ledge comparison diagram are two important diagram in geology diagram, and they are applied to mine production, and they are basic foundation and precondition that we solve question on geology. According to application, geology columnar section may be classified as synthesis columnar section and drill columnar section, and there are the same way to plot diagram. Ledge comparison diagram is a diagram based columnar section’s data, and it’s link is to stand out ledge information.With object- produced application point of view, this paper analyzes characteristic of drill’s data, sums drawing’s class, data modeling and knowledge system of auto_plotting drawing and elaborates the fundamental principle of auto-plottinggeology columnar section and ledge comparison diagram by computer, describes data organization structure, symbols design, the method of filling symbols in columnar section and the method of words’ auto_ newline and presents a valid algorithm for plotting buffer line based on segment, then explains the method of auto-plotting comparison diagram. According to the theories, the system of auto-plotting columnar section and comparison diagram is developed with object-oriented program design method, which provides the interface with other GIS softwares and reaches the aim of data sharing. The system has been applied successfully in practice.更多还原
