摘要
为了提高传统资源量估算方法、资源量动态估算、可视化及分析程度低、估算方法的问题。该文通过三维可视化技术对传统资源量估算方法、方式进行更新与改造,用真实三维地质几何模型取代抽象的规则几何体,研究并实现一种新的适合铀矿资源勘查及储量分类的资源量三维可视化动态估算及分析方法,使传统资源量的估算方法更加的科学。认为资源量估算过程及结果在传统资源量块段法中是受矿体块段、形态、厚度及空间位置因素的决定,在地质统计学储量估算—普通克里格法储量估算中受二维剖面图矿体边界线圈、矿体积体、三维空间矿体模型建立及矿体模型变差函数品位插值的系数等决定。该文以新疆某铀矿为例,通过传统块段法与Quanty U块段法对比得出误差在0.14%,传统块段法与普通克里格法对比得出误差在0.8%,两个误差均在10%合理误差范围之内,所有Quanty U软件块段法、普通克里格法资源量估算方法及三维建模地质矿体建模可以在砂岩型铀矿找矿工作中应用。
In order to improve the traditional estimation method of resource quantity,dynamic estimation of resource quantity,the low degree of visualization and analysis,the problem of estimation method. In this paper,the traditional methods and methods of resource estimation are updated and reformed by means of 3 D visualization technology,and the abstract regular geometry is replaced by the real 3 d geological geometry model,a new 3 D visualization dynamic estimation and analysis method for uranium resources is studied and realized,which makes the traditional estimation method of uranium resources more scientific. It is considered that the process and results of resource estimation are determined by the factors of ore block,shape,thickness and spatial position in the traditional resource block method,in the estimation of reserves by geostatistics method,such factors as boundary coils of Orebody,orebody volume,3 D orebody model and grade interpolation coefficient of variation function of orebody model are determined.In this paper,taking a uranium mine in Xinjiang as an example,through the traditional segment method compared with Quanty U block segment method error in 0.14%,the traditional segment method with ordinary kriging method contrast it is concluded that error of plus or minus 0.8%,10% error in within a reasonable range of error,all Quanty U software segment method,ordinary kriging method resource estimation method and three dimensional modeling geological ore body modeling can be applied in the sandstone type uranium deposit prospecting work.
