Firstly, the stope vacancy was monitored using CMS, taking cavity measured data as foundation, cavity three-dimensional model of the stope opening was created using Surpac software and gain the stope three-dimensional configuration and the actual boundary accurately. Then, the stope designed model and ore-rock interface digital terrain model were established according to the stope design material. Finally, using ore-rock interface DTM to cut cavity model or through Boolean calculation among the models, ore remains, mining total volume, mullock, backfilling, pure ore and dilution rate of stope N3-4 were calculated accurately, thus the large-scale stope mining index visible calculation was realized effectively.
