Abstract: With the rapid development of computer and information technology, many excellent computer-assisted design techniques and methods have gained wide application in mining industry, hereby bringing innovation in production design concept in mining circle and greatly improving the production design and management level of mining enterprises. Guided by this technical development trend and in combination with a real case of a large domestic mine, the paper studies the spatial distribution of ore grade by using geological statistics and three-dimensional visualization modeling technology. The results indicate that the model that is built is reliable, with the results calculated based on it accurate, and can be used to assist geological and mining engineers in resource evaluation, mining design and planning.

Key words: Geological statistics, Variant function, Visualization, Grade distribution
