矿体储量及其计算参数的误差公式和金属储量误差的回归模型

据个旧锡矿开发勘探资料,在计算机上实现不同网度稀空试验的结果、讨论了误差估计问题,提出了矿石品位、矿体厚度、矿体投影面积、矿体体积和金属储量等误差估值公式。以实例建立了不同穿透样锡品位变化系数值的金属储量误差与工程数量的回归模型,并将其应用于金属储量误差估计和工程效果的预测。

ESTIMATION OF THE ERROR OF RESERVES AND ITS REGRESSION MODEL

Using the data abtained in the exploitation and exploration of Gejiu Tin Mine,we have done the tests of rarefied densities of all possible projects under different densities on computers. Based on the results of these tests, we have advanced the estimate formula of ore grades and thickness, projected area and volume of ore bodies, and metallic reserves. Taking the large type of compound lenticular skarn ore deposit-sulfide deposit as an example, we've established the regression model of the metallic reserves error and the number of projects with different variation coefficients in tin grade of penetrating samples, and applied this model to the error estimating of metallic reserves and the forecasting of project effectiveness.
