在煤矿设计、建设和生产的过程中，需要解决一系列的煤矿地质问题，在这些过程中积累了大量的煤矿地质资料。通过对这些资料加工整理，提取有用的煤矿地质信息对于提高煤矿资源的合理利用，预防地质灾害的发生至关重要。目前许多煤矿地质部门的数据管理方式还很落后，许多煤矿地质资料仍然以散乱的方式管理，实现信息化的需求极为迫切。煤矿地质信息化涉及地质学、测绘学和计算机科学等众多学科，而这些交叉正是地理信息科学的重要研究内容。因此采用GIS技术整合现有的煤矿地质信息是目前煤矿地质系统开发的趋势。目前国内外应用专业GIS平台进行煤矿地质信息管理和分析的系统仍比较少。 本文研究了煤矿地质空间数据库的设计和实现方法，利用空间数据库管理煤矿地质相关的图形数据，利用关系数据库管理煤矿地质资料、用户权限和系统日志等非空间数据。研究了基于GIS的可视化与空间分析方法在煤矿地质领域的应用。将地质钻探数据统一组织，以二三维一体化的方式展示给用户，实现了钻探信息的可视化；利用表面建模方法，对煤矿钻探底板数据进行空间插值，生成多层DEM模型，提出了一种运用栅格计算处理岩层缺失现象的方法，实现了对多层DEM地质建模方法的扩展；为了实现地质剖面的三维可视化表达，本文提出了一种地质剖面三维建模的技术路线，通过构建二维剖面线框数据，利用左转算法构建二维剖面面要素，利用仿射变换实现二维地质剖面面要素的三维恢复，构建了三维地质剖面并存储为Multipatch要素类型，实现了剖切分析以及地质剖面三维恢复；实现了基于Multipatch的层状地质体建模；研究了储量管理的工作内容以满足煤矿日常生产的需要。 在理论研究的基础上针对陕西省红石岩煤矿的项目整合需求进行了系统的需求分析、总体设计和详细设计。采用面向对象的统一建模语言规范需求分析和设计阶段的各种建模描述。最后采用ESRI公司的ArcSDE空间数据库引擎和Oracle数据库存储煤矿地质相关的空间和非空间数据，利用C#语言和ArcEngine组件二次开发，实现了系统设计的功能，取得了较好的效果。 第一章绪论部分介绍了论文的选题背景与研究意义。 第二章介绍了论文涉及的关键技术和技术路线。本文涉及的主要关键技术包括统一建模语言，空间数据库建模，组件式开发技术和多元数据处理。 第三章探讨了基于GIS的煤矿地质信息可视化方法与空间分析方法。 第四章系统需求分析，描述了业务流程，分析了系统角色定义和系统的功能需求。 第五章系统设计及功能实现，包括数据库设计、总体设计、详细设计和功能实现。 第六章总结了论文的研究成果，对进一步的工作提出展望。

In the process of design, construction and production of coal mine, a series of coal mine geological problems need to be solved. Thus accumulate a large number of coal mine geological data. Through the data collation processing, extracting useful coal mine geological information to improve the rational use of coal resources, it is also the key of geological disaster prevention. Data management mode of geological data in many mine geology department is still very backward, coal mine data management is still in scattered way. The demand to realize informationization is extremely urgent. Coal mine geological information relates to many subjects, such as Geology, Surveying and Mapping Science and Computer Science, and the content cross is the research of Geographical Information Science. So using GIS technology to integrate coal mine geological information is the trend of coal geological system development. At present, system using professional GIS platform for mine geological information management and analysis is still relatively less. This paper studies the design and implementation method of coal mine geological spatial database, the way using the spatial database to manage graphics data that coal mine geology related. Relation database was used to manage coal mine geological files, user information and system logs and other non-spatial data. The visualization and spatial analysis method based on GIS using in coal mine area is also the study content in this paper. The unified organization of geological drilling information, showing to users in integration way in two and three dimensional, the visualization of drilling information is realized; using the surface modeling method, spatial interpolation of the coal mine drilling floor data, the Multi-DEM model is constructed. To deal with the rock loss phenomenon, a method by using grid calculating to extend the Multi-DEM geological modeling method is propused. To display the geology profile and solve the problems of 3D profile modeling in the application, a technology of building geology 3D profile model is proposed in this paper. By building 2D Profile Frame FeatureClass, using Left algorithm for constructing two-dimensional profile, using affine transformation for reconstruct 2D profile polygon FeatureClass, constructs a 3D geological section and stores as Multipatch FeatureClass, realizing cutting analysis and geological profile reconstruction. The stratified geological body modeling is realized based on Multipatch. Reserves Management can meet the needs of daily production of coal mine. The requirements analysis, overall design and detailed design are based on the system integration demand of Shaanxi Hong Shiyan Coal Mine. Using unified modeling language object-oriented to specify modeling description of requirement analysis and design stages. Using ESRI company’s ArcSDE spatial database engine and Sun’s Oracle database to store spatial and non-spatial data, using C# language and ArcEngine component technology to develop the system, and good result is achieved. The first chapter introduces the background and significance of this research. The second chapter introduces the key technology and technical route of this paper. The key techniques include the unified modeling language, modeling of spatial database, component development technology and multivariate data processing. The third chapter discusses mine geological information visualization method and spatial analysis method based on GIS. The fourth chapter includes system requirements analysis, business process analysis, describes system role definition and functional requirement of the system. The fifth chapter is about system design and function implementation, including database design, overall design, detailed design and function realization. The sixth chapter summarizes the research results of the paper, puts forward the prospects for further work.
