寺家沟金矿床基于Mircomine的可视化建模及距离幂次反比法的资源量估算
|
摘要
在汇集寺家沟金矿床的地质、钻探及采样分析的资料基础上,借用Micromine平台,建立了矿区的地质数据库并以可视化方式呈现。在排除特高品位的情况下,参考K1金矿体特性,进行了其他矿体的三维圈连、矿块三维建模、矿块赋值、资源量估算。研究表明:在Micromine平台上的矿体三维模型,可以直观的展示矿体的三维空间形态,并形象地呈现出延伸的趋势;为了减少矿块估算中的主观干扰,利用统计学的距离幂次反比法,针对矿块赋值,能更为合理、客观地赋予各个矿体模块品位信息,得出了客观合理的资源量估算结果。
After collected geological,drilling and sampling analysis data of Sijiagou gold deposit,this paper set up and visualized a geological database for the mining area based on the platform of Micromine.With erratic high grade excluded,and considering the characteristics of K1 gold orebody,the authors conducted 3 D delineation and connection,3 D modelling of ore blocks,value assignment of ore blocks and estimation of resources.The results indicated that the 3 D model on Micromine platform could give a visual representation of the three dimensional space pattern of the orebody and visually display the trend of extension;in order to reduce the subjective interference on ore block estimation,the statistical inverse distance weighted method could assign grade information to each ore block module in a more reasonable and more objective way,in order to ensure that the results of resource estimation are more reasonable and more objective.
