Floating Cone Algorithm with A concrete mining example

Economic factors such as costs and expected revenues, which vary with grade and block location, are then applied; the result is an economic block model. Some of the blocks in the model will eventually fall within the pit, but others will lie outside. Of the several techniques for determining which of the blocks should be included in the final pit, the most common is the floating cone technique. In two dimensions the removal of a given ore block would require the removal of a set of overlying blocks as well. All of these would be included in an inverted triangle with its sides corresponding to the slope angle, its base lying on the surface, and its apex located in the ore block under consideration. In an actual three-dimensional case, this triangle would be a cone. The economic value of the ore block at the apex of the cone would be compared with the total cost of removing all of the blocks included in the cone. If the net value proved positive, then the cone would be mined. This technique would be applied to all of the blocks making up the block model, and at the end of this process a final pit outline would result.
