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
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.
