地质剖面图和煤层底板等高线图是最主要的地质图件，是煤田勘探和煤矿生产、管理的重要基础资料。 传统的地质剖面图和平面图主要是手工绘制，不仅效率低而且精确度不能达到要求。随着计算机辅助制图技术和地理信息系统的迅速普及，计算机绘制剖面图和平面图已水到渠成，其绘制技术和算法也在逐渐成熟。 本次设计在分析和总结煤田勘探和煤矿生产地质资料基础上，建立了能够满足自动生成地质图件的数据库。在总结前人研究成果的基础上，以MAPGIS为开发平台，以Visual C++为开发语言，完成了自动生成勘探线剖面图和煤层底板等高线图的成图模块。其中剖面图绘制中，解决了断层和地层协调问题两大技术难题。以自动生成的剖面图为基础，采用剖面法，完成煤层底板等高线图的自动绘制，较好地解决了断层和褶皱问题。最后利用剖面图和煤层底板等高线图中控制点一致原则，实现了剖面图和煤层底板等高线图的互动，达到了人机交互、互相修改图形的目的。 最后，以铜川矿务局下石节煤矿的地质数据，进行了实际验证，自动生成的剖面图和煤层底板等高线图符合实际情况，能够满足要求，并能实现平、剖互动，达到了预期的效果。

The geologic section and coal seam floor contour map are the uppermost geological maps, it is the important basic data that guides to coal exploration and colliery produce and management. The traditional geologic section and coal seam floor contour map are manual draw, not only the efficiency is low and the accuracy can't attain request. Along with the quick popularization of the Computer-aided drawing technique and the geography information system , computer draws ichnograph and geologic section already as naturally as a ditch is formed when water flows along, the draw technique and arithmetic is work up to maturity. Based on analyzing and summary this design built up a geology database which can satisfy auto-generating. Sum-up predecessor,I used MAPGIS and VC++ completed the auto-generating of geologic section and coal seam floor contour map.Among them,I solved the fault and geologic strata moderate problems in the auto-generating of geologic section. On the section foundation, adopted section method, drawed the coal seam floor contour map ,I solved the fault influence and anticline or syncline problems. Make use of control points in section and coal seam floor contour map, carry out the interaction of two kinds of maps,and attain interactive and modify with each other. The end, I done actual verification with geology data of XiaShiJie mineral District in TongChuan , the auto-generated maps of geologic section and coal seam floor contour map can match the actual circumstance,satisfy the request, carry out the interaction of two kinds of maps, and reach the anticipant purpose.
