Abstract: Combined with the specific example of Tandan copper mine, summarize pillaring methods and application conditions, through the ground pressure monitoring, selecting a reasonable structural parameters of the stope, utilizing the effective roof support technology, and create all the three dimensional visualization model entities of mine project by DIMINE, and on this basis, make pillar visualization recycling design, the results have played a guiding role for the mine actual production.

Key words: DIMINE, Entity model, Ore pillar recycling, Ground pressure monitoring
