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.

采用CMS探测三维采场空区，以空区实测数据为基础运用Surpac构建采空区三维可视化模型，获取采场空区的三维形态和实际边界；运用采场设计资料，建立采场回采设计模型及矿岩边界模型，通过模型间的布尔运算，计算出采场存留矿量、回采总体积、采下废石量、采下充填体量、采下纯矿石量、回采总量及回采贫化率等，从而有效地实现了大规模采场回采指标的可视化计算。
