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。
According to the exploration data of Gejiu tin mine, the results of the levitation experiment with different mesh degrees are realized on the computer, and the error estimation is discussed. The error estimation of ore grade, ore body thickness, ore body projection area, ore body volume and metal reserves are put forward Value formula. A regression model of metal reserves error and the number of projects with different values of coefficient of variation of sample tin penetration was established with examples and applied to the estimation of metal reserves errors and the prediction of engineering effects.
