摘要: Geological and economic modeling of an ore body also optimization the depth at which transition is made from open-pit to underground mining important part design process in large massive deposits. In this paper, a geological block model Chah-Gaz iron deposit located Iran was first created based on cut-off grade. Then with considering parameters derived. The used determine mining. determination mathematically modelled for case study. objective function chosen be maximization total profits earned combination both deposit. problem finally solved by developing MATLAB code. results obtained indicate 450 m.
