基于3Dmine技术建立三维地质模型及储量估算
|
摘要
3DMine矿业软件的数据库格式是依据各种勘探工程编录的格式而定的,将收集的地质资料,包括钻孔、坑道等空间参数数据,及所揭露岩石性质特征;矿石品位分析数据和地质剖面图等数据,导入数据库当中,通过3Dmine软件将数字形式的勘察资料变换为三维图形,从而建立三维地表模型和矿体模型。并在构建好三维模型的基础上,运用地质统计学变异函数分析、普通克里格法等理论方法相结合对矿体储量进行估算。
The data bank pattern of 3 Dmine software is set up according to the various exploration documentation,the collected geological data,including drillhole,tunnel,etc,space data,and rock character,ore grade analysis,geological section data,etc,are inducted in it.The exploration information in digital form is converted into the 3 D image by the 3 Dmine software in order to set up the 3 D surface model and orebody model.Based upon the 3 D model,the reserves estimation of orebody is carried out with variation function analysis of geological statistics and in combination with ordinary kriging,etc.
