地质统计学在稀土矿储量计算研究应用
|
摘要
近些年,随着数字矿山的迅速发展,地质统计学在数字矿山中的应用越来越重要。建立稀土矿数字化矿山,采用地质统计学方法对稀土矿储量及参数进行验证,建立变异函数模型,对稀土实验模块分别采用普通克里格法和距离幂次反比法进行储量计算分析,最终两者计算结果和原始方法计算结果基本一致,从此稀土实验模块得出普通克里格法计算储量更加合适。通过准确对比分析得出,地质统计学不仅能在有色金属矿储量计算使用,而且在稀土矿储量计算中也具有科学性和准确性。
In recent years, with the rapid development of digital mines, the application of geostatistics in digital mines has become increasingly important. The digitalized mine is established for a rare earths mine in Southern Jiangxi Province. Geostatistical method is used to verify the reserves and parameters of the rare earth mine. A semivariogram model is established, and the ordinary Kriging method and distance inverse power method are used respectively to calculate and analyze the reserves of the rare earth experimental module. The final calculations by above two methods are basically the same as the result calculated by the original method. It is more suitable to use the ordinary Kriging method to calculate the reserves.The conclusion drawn by accurate comparison and analysis is that the geostatistics can not only be used in the calculation of reserves of non-ferrous metals, but also has scientificity and accuracy in the calculation of reserves of rare earths.
