The author, taking the primary data models as an entrance, proposes a solid mineral reserve estimating method based on integration mode of spatial data models. The method connect (1) the series section model with traditional reserve estimating methods, (2) volume and block model with the geological statistic method of reserve estimating method, (3) section-tin model with random mineral mesial chart, (4) DEM with mineral area simulating, which integrate multi- solid mineral reserve estimating method as a whole, implementing the mineral configuration and estimated diggings 3D visualization. The method can not only satisfy internal traditional reserve estimating methods, but also combines...
