Mine scheduling for metallic open pit mines

Minerals are nonrenewable resources formed over millions of years. Therefore; minerals must be produced with planning efficiently prioritizing the public interest within the frame of principles of occupational health and safety in accordance with environment friendly, rational and economical rules without loss of resource by taking needs of the country into consideration (TMMOB, 2019). An effective planning must comply with changing cost and product value in the fastest way possible and yield the highest production with highest current value possible obtained from reserve. In this study, production plan which make an open pit mine to make production with maximum profit throughout its mine life are examined by means of computer program. A database is set by data acquired from borings made in the field. Grade-tonnage calculations are made by geostatistical analyses (statistical and variogram analyses) and distribution of ore within the mineral deposit is determined by kriging method. Costs estimated for mining and enrichment phases are determined. Nested pit is formed by changing ore price and ore production sequence is determined by examining changes within pit boundaries.
