mine open pit production planning

Risk Management Incorporated to Life

Open pit mine design and production scheduling deals with the quest for most profitable mining sequence over the life of a mine The dynamics of mining ore and waste and spatial grade uncertainty make predictions of the optimal mining sequence a challenging task Valuation and related decision-making in surface mining require the assessment and management of orebody risk in the generation
