In view of poor visualization ability and computability of the traditional mine 2D design, a stope 3D visual design which combines the 3D mining software and the Cavity Monitoring System (CMS) is proposed. First, the shape of the cavity is obtained by CMS, to build a local geological model of the stope. Then, a 3D model of the pillar is built by Boolean operations of solid models and the local geological model. Based on this, a preparatory arrangement is obtained. Finally, a full 3D visual design of the stope is achieved. A medium-to-long hole blasting design is carried out by CMS and Surpac software in the E2-3 stope of some metal. First, pillar sections of the stope are acquired quickly in Surpac. Then, a blasting design database is constructed, and a medium-to-long hole blasting design of each section is made. Finally, a blasting report is generated. According to statistics, the volume of stope and the amount of explosives are obtained, with explosives consumption being calculated as about 0.892kg/m3, which agrees well with the empirical value. The practice shows that this method can well determine the pillar boundary in the pillar extraction with visualization, which the traditional design is dificult to achieve, and it is also convenient.

articleAbstract=针对矿山传统二维设计方法的不直观、可计算性差等缺点，提出了三维矿业软件与空区激光探测系统相结合的采场三维可视化设计方法。首先通过空区激光探测系统（CMS）获得采空区的实际形态，在Surpac软件中构建采场局部地质模型，将探测所得实体模型与局部地质模型进行布尔运算后获得矿柱的三维模型，在此基础上进行了采准工程的布置，实现了采场设计全程三维可视化。以某金属矿山为例，运用CMS和Surpac软件对E2-3采场进行了中深孔爆破回采方案设计，在Surpac软件中快速获取矿柱剖面，通过建立爆破设计数据库，对各剖面进行了中深孔爆破设计，最终生成了爆破设计报告。根据统计获得设计采场体积及所需炸药量，经计算炸药单耗约为0.892kg/m3，该指标与经验值较为吻合。实践证明，该方法能够较好地解决矿柱边界难以确定，传统设计三维显示不够直观等问题，并且计算比较方便，具有重要的推广应用价值。,
