متن يادداشت

The Abu Tartur Plateau lies between the Kharga and Dakhla Oases in the Western Desert of Egypt and contains the largest phosphate deposit in the country. The estimation of the reserves in the lower phosphate horizon is the main objective of this study. A compound spherical model was fitted to the horizontal variogram for P2O5%, and simple spherical models to the horizontal variograms of both thickness and accumulation. The estimates for the total tonnage, the total phosphate content and the mean grade within the central part of the lower phosphate horizon have been obtained. The two dimensional block kriging of the deposit was carried out to obtain estimates for blocks of 400m x 400m x 1m dimensions. The kriged estimates and the corresponding relative kriging standard deviation for a total of 3752 blocks were computed. Finally, using the distribution of kriged block estimates, a grade-tonnage curve based on the selective mining units of 25m x 25m x 1m dimensions was constructed. (Abstract shortened by UMI.)
