MapGIS中的DTM模块在非金属矿资源储量计算中的应用——以广西融安崖脚白云岩矿为例

Application of DTM Module in MapGIS in the Calculation of Reserves of Non-Metallic Mineral Resources——Take the Dolomite Mine at the Foot of the Cliff in Rong’an,Guangxi as an Example

结合工作实例,介绍了基于MapGIS的数字地面模型(Digital Terrain Model,DTM)分析技术在非金属矿山资源储量计算的应用方法。简要介绍白云岩矿体GRD模型建模过程,分类分级估算白云岩矿体资源量,与剖面法资源量估算结果进行对比。MapGIS中的DTM技术应用于非金属矿的资源储量估算后,结果准确,方法简便实用,提高工作效率,是建立数字化矿山和绿色矿山,实现矿山企业生产、经营、管理的信息化、智能化的方法之一。

This article introduces the application method of Digital Terrain Model (DTM) analysis technology based on MapGIS in the calculation of non-metallic mine resource reserves,combined with work examples.Brief modeling process of GRD model for dolomite ore body,classification and grading estimation of dolomite ore body resources,and comparison with the results of profile method resource estimation.After applying DTM technology in MapGIS to estimate the resource reserves of non-metallic minerals,the results are accurate,the methods are simple and practical,and work efficiency is improved.It is one of the methods to establish digital mines and green mines,and to achieve informationization and intelligence in the production,operation,and management of mining enterprises.
