About this document

Defining Ultimate Pit Limits in Mining by Waqar Anwar is a document available to read on EtoBox.

The document discusses methods for determining optimal pit limits in open-pit mining. It describes: 1) Hand methods that involve analyzing vertical cross-sections to find the stripping ratio where costs equal revenues, defining the pit boundary. 2) The floating cone technique used in computer models, where a geometric shape is "floated" through a block model to maximize net present value by including all blocks with positive value. 3) An example application comparing the hand method and floating cone o
