The determination of optimal production capacity for open-pit mines is influenced by various economic and technical factors highly susceptible to uncertainties. To effectively address the impact uncertainty on planning, this study develops a planning model coal mines, based theory economies scale incorporating multiple constraints. A novel method proposed quantify propagate uncertainties key control factors, alongside comprehensive analysis framework total revenue. Using large-scale mine as case study, relationships calculation tables are provided. Based this, mathematical expression revenue under influence formulated, range calculated. application demonstrated through revealing that in costs prices (-13.05%, +27.68%) (-10.79%, +10.79%) respectively. Subsequently, risk-tolerant recommendations proposed, mitigating determination.
