Surpac软件在三维地质建模中的应用

介绍了Surpac软件在数字矿山地质建模上的应用.以某矿山为例,根据矿区的原始资料,利用Surpac软件,建立了矿区数据库、实体模型、块体模型,清晰直观地反映了矿体的空间分布特征.研究涵盖了特异（高）值的分析与处理,块体属性的建立及其大小参数等的确定,矿体模型、岩性模型等在指导矿山工程布置上的运用等方面.最后,着重比较了Surpac与传统方法的储量计算结果,数据表明Surpac模型可靠,计算正确,可用于资源评估、资源动态管理、采矿设计及计划编制等工作.

Application of Surpac software for 3D geological modeling

The authors depicted the application of Australian Surpac software in geological modeling for digital mine. Taking a mine as a ease study, and with the help of the original data of the mine and Surpac Vision, the authors established mine database, entity model and block model, it could reflect the space distribution features of ore body clearly and intuitively. The authors conducted following aspects ： the analysis and processing of erratic high-value, the setting up of block properties, the determination of parameters, and the application of ore body model and lithology model in mining engineering layout. Finally, the calculation of reserves was especially compared between Surpac and traditional methods. The result showed that the model was reliable and correct, and it could be used for resource assessment, resource dynamic management, mining design and compilation of plan.
