摘要
将地理信息系统(GIS)应用于矿山则称矿山地理信息系统,或矿山空间与资源信息系统。它是以计算机为基础,应用测量,摄影测量与遥感等技术采集信息,并通过机助制图和图象处理等辅助手段,紧密结合矿山的空间与资源特征构建起来的一种信息系统。它具有对矿山资源与环境信息进行采集 存储 处理,建立矿区数据库及软件系统,实现对信息系统查询检索 综合分析 动态预测和评价 信息输出等功能,从而为矿区环境工程和矿产资源开发管理进行规划 判断和决策提供科学依据。本文讨论矿山信息的种类和特点,矿山地理信息系统(GIS)的功能要求,可行的数据结构,以及矿山GIS的建立与应用等问题。

The types and characterestics of data information in mines the functional require-
ments and a available data of mine Geographic Information System (GIS) are discussed
in this paper The surface terrain and any swbsurface strata such as a coal seam are
represerted by Seperate Triangulated Irregular Networks (TIN) Anyattribute datanyo
be assigned to the TIN's can be stored in polygon overlays Any remalning spatial data
are stored as link strings or nodes in a cubic grid cell skeletal structure with efficient
topologic description Themost valuable application of the mine GIS is the production
of map products in either horizontal or vertical planes Engineering data including
lengths areas or volumes can be calculated The design analysis and environmental
evaluation can also be accomplished using the system
