INTEGRATED COAL-MINING OPERATIONS PLANNING: MODELING AND CASE STUDY ANTO ˆ NIO CARNIATO 1 AND EDUARDO CAMPONOGARA 2 1 Coal Industry Association of Santa Catarina, Criciu´ ma, SC, Brazil 2 Department of Automation and Systems Engineering, Federal University of Santa Catarina, Floriano´ polis, SC, Brazil Coal production, processing, and blending are partly addressed by existing models for operations planning of mining enterprises. To this end, this article proposes a (mixed-integer) linear programming formulation for integrated planning of mining operations over time and with stochastic parameters. The model is applied in a rolling- horizon framework (which allows for corrective measures in response to unanticipated events) and with chance constraints (which render the model more robust to uncertainties). The robust- ness of the model was evaluated in a case study based on the actual operations of a real-world mining company.
