ABSTRACT
The present package includes a rich set of integrated modules for managing mine data like borehole location, down hole metric samples and assays. Checklists are prepared for selected boreholes and intermediate files are used for constructing semivariograms and contour maps and for visualizing the ore body, surface topography, overburden and chemical assays.
At a selected block size, kriging and reserve estimation of the ore are conducted in addition to the cumulative and grade/tonnage/cut off curves. For the sake of completeness, the estimation of deposits by triangle as one of the classical method is provided.
The blending operation aims to mix ores collected from different mine faces so that the final mixture assays fulfill some metallurgical constraints. Linear Programming is applied for solving such problems. The optimal solution (if present) is that which minimizes the objective function (cost of ore extraction) under the given constraints. The package is illustrated through a hypothetical ore deposit simulated under controlled condition, therefore, it can be used for optimizing study as well as educational purposes.
