基于GIS的多工程矿体圈定模型分析与实现

平行断面法储量计算是矿山中常用的储量计算方法之一,断面图上进行的工程间矿体圈定是其中的关键环节之一。以往多采用手工模式进行,存在着工作量大、周期长等不足,不利于储量计算的快速实施。为了提高矿山信息化程度,在基于GeoviewGIS的矿山资源信息系统中尝试设计了计算机辅助圈定矿体的工作模式,针对福建紫金山成矿模式进行具体实现,并进行了矿体圈定验算。实践表明,该方法能较好地满足该类矿山的相关需求,具有较好的准确度和效率,能大幅提高工作效率和信息技术应用水平。

Analysis and Development of Multi-project Ore body Delineation Model Based on GIS

Parallel cross-sectional method is commonly used on mine reservoir calculation,of which the ore-body delineation based on the sectional drawing is one of the key procedures.Since the procession by hand is hard and time-consuming,it is a large obstacle to the realization of reservoir calculation in the computer.In the project of mineral resource information system based on Geoview,the way of ore-body delineation aided by computer is designed and applied in the Zijinshan mine.The practice shows the feasibility of GIS and the precision in the ore-body delineation.
