Estimating the Total Reserves,he limits of the orebody are known a priori or not. After presenting the concept of extension variance, the first part of the chapter treats different approximations for evaluating the global estimation variance while the second half considers the question of “optimal” drilling grids.躺下残杀 发表于 2025-3-27 03:15:33
Herder and the Misuse of Language,he other one is skewed..The formulas for the variance of a point within a block and of one support v inside another V are then given. Krige’s additivity relation is proved. Then we see how the regularized variogram is related to the point support variogram. An exercise illustrates the effect that regularizing has on the variogram.Defense 发表于 2025-3-27 05:40:16

Textbook 1998e, are familiar with basic probability and statistics, and matrix algebra needed for solving linear systems. Some reminders on these are given in an appendix at the end of the book. A set of exercises is integrated into the text.束缚 发表于 2025-3-27 18:27:35
Herder and the Misuse of Language,K estimators is proved. For ordinary kriging, the formula for the slope of the linear regression of the true grade on its estimate is given, and its importance in relation to conditional unbiasedness is discussed. Lastly, kriging is shown to be an exact interpolator.Lignans 发表于 2025-3-28 00:16:56

Introduction,d for good estimators, particularly when selective mining is being used. The economic impact of the support and information effects on reserve calculations is stressed. Lastly some case studies comparing geostatistics with other estimation methods are reviewed.假 发表于 2025-3-28 06:27:52
Regionalized Variables,nary and the weaker intrinsic hypothesis) are introduced. The . and the . are defined. The problem of how to decide whether to treat a variable as stationary, intrinsic or nonstationary is discussed. Some of the basic properties of the spatial covariance are introduced in this chapter as they are heAgronomy 发表于 2025-3-28 12:55:47
The Variogram,e.g. zone of influence, behaviour near the origin, anisotropies, presence of a drift, etc.). The common variogram models are presented. Images of variables having some of these variograms have been simulated to highlight the differences between the models. The formula for calculating the variance of
