Abstract
Consumable supplies in mines (explosives and explosive devices, oil, lubricants, rubber, protective devices, spare parts for machinery and equipment, flotation reagents, etc.) should be sufficient for stable production. However, for mining operations, supplies are burden costs, as storing supplies increases operating costs. The logical question is how to achieve the balance between mine production stability and minimization of costs of supplies, that is, how to optimize supplies. The paper presents a quantitative model of stochastic supplies optimization as a possible answer to this question. The application was demonstrated in the specific case of polymetallic ore lead, zinc, copper, and silver mine flotation with value indicators.
