贵州松桃李家湾锰矿三维建模及储量估算

3D visualization technology is applied constantly in geological field with the rapid development of computer technology. This paper introduces the process of 3D modeling of Li jiawan manganese deposit in detail, and designes and implementes the resources reserves estimation method combining with spatial statistical methods. The method completes profile cutting automation, and smart parses profile with human-computer interaction, not only greatly improve the work efficiency, and intuitively and accurately reproduce the Li jiawan manganese deposit geological structure and spatial distribution characteristics. The method divides ore body block scientifically and reasonably in the form of "visual", and establishes the grade model of ore body, then estimates resources reserves. Results show that the estimation result used this method is scientific and reasonable, efficient and accurate, and can be used for verfication of traditional geometry method, and that has the generalization and applicability, and can be applied to other deep mineral resources reserves estination in Guizhou, and auxiliary decision-making exploration and mining work.
