摘　　要：与传统空区探测方法相比,CMS是一种针对单个明确目标的探测方法,借助Surpac等矿业软件可以实现对矿山回采指标的可视化计算。本文介绍了采空区CMS精密探测的基本原理以及采空区三维模型的构建方法,分析阐述了采场环境因素与测点的选择对CMS探测效果的影响以及模型的后期处理,最后以冬瓜山铜矿某采场为例,从采场周边超挖量、存留矿石量及回采贫化指标的计算角度提出了采场回采可视化的构建方法。Compared with traditional detection methods of cavity,CMS is a detecting method for a single clear objective.Mining computing of visualization can be achieved by Surpac or other mining softwares.In this paper the basic principle of CMS,as well as the method of constructing 3D cavity model is described,and the effect of the mining environment factors and the choice of detecting postions on the CMS detection and post-processing of model are analysed and described.Finally,taking Cuprum mine of Dongguashan certain stope for an example,the improved mining visualization method is advanced from calculation of the ming indexes of stope surrounding over-excavation,residual ore amount and the mining loss.
