摘要
利用Surpac软件将某铜矿床的钻探工程数据进行处理,建立其地质数据库,铜矿体的三维模型及品位变异函数模型,结合块体估值技术选择合理的地质统计学方法估算其资源量,并与距离幂次反比法估算结果进行对比研究,分析铜矿体不同方向上的品位变化趋势。结果表明,基于Surpac软件与地质统计学方法对该矿床进行资源量估算,结果可靠,操作简便,工作效率高,有利于推动地质统计学在国内矿产资源评价中的应用。
The drilling engineering data of a copper deposit was processed by Surpac to establish geological database,three-dimensional orebody model and grade variogram model.With block valuation techniques,a reasonable geological statistics was selected to estimate the resources of copper deposit.And compared with the estimation results of distance power inverse ratio method,the grade trends in different directions of copper orebody were analyzed.The results showed that resource estimation based on Surpac software and geostatistics was easy to operate with reliable results and high efficiency,which was beneficial to promote the application of geostatistics in domestic mineral resources assessment.
