摘要
矿床三维模型是“数字矿山”的基础,是矿床的数字表征。借助国际矿业软件Surpac建立了某矿山地质数据库,在此基础上构建了矿区地表、断层、矿体、空区和巷道的三维模型以及品位块体模型。针对品位块体模型采用普通克立格法对矿体金属元素品位进行估值,运用估值结果分别按各金属元素和中段进行了储量计算,并与矿山实际勘探获得的储量进行了对比。结果表明,采用Surpac软件所建模型可靠,计算结果准确,可用于辅助矿山进行资源评估、采矿设计以及计划编制等工作。
Three - dimension models of deposit are the foundation of ＂digital mine＂ and the digital characterization of deposit. The authors established the geological database for a mine, based on which three dimensional models for the surface, fault, orebody, cavity and roadway and the grade block model were constructed. Estimation was made based on the grade block model of the grade of metal elements in the orebody by Kriging method. The estimation results were used to cal- culate the reserves for each metal element and each sublevel, which were then compared with the reserves obtained in the real exploration of the mine. It is shown that the models established using Surpac software are reliable and the calculation results accurate, and can be used to assist in mine resource assessment, mining design and scheduling.
