摘　　要：引入关系数据库和GIS自动编图技术,改进传统的垂直断面法储量计算过程,可实现矿山储量计算和勘探线剖面计算机辅助成图的同步和一体化。在共用的矿山地矿信息点源数据库平台基础上,通过设置本地数据库,形成GIS操作时的外挂属性库,用来保存储量计算和机助成图过程中的动态数据。储量计算中的每一步骤中,用户以GIS为操作界面来同步实现对空间图元和外挂属性的操作,这其中对工程样段组合、矿体边界圈连和剖面制图综合等开发了大量自动化辅助功能。储量计算的各步完成后,勘探线剖面图和储量报表即同步生成。这种改进的工作方式实现了垂直断面法全过程的计算机辅助化,将提高这一传统方法的应用效率。Applying relational database and GIS auto - mapping to improve process of vertical section method in conventional mineral reserves calculation can achieve integration of reserves calculation and computer aided mapping of vertical sections. The working was based on the common point source database of mine geology and ore information. The local database was a smaller external database, which stored the dynamic data for GIS operating and attribute calculation. In the each step of the reserves calculation, with GIS as an operating interface, user can operate spatial data and external attribute data synchronously. Quite a few auto - techniques, such as combining of sample, joining and closing of ore body boundaries, and map generalization, are developed. Vertical section maps and of reserves calculation reports were formed together after the process was finished. This improved working approach realizes the computerized entire process of the vertical section method, and enhances the practical efficiency of this conventional method.
