A binary mathematical model for production scheduling in cut and fill mining

Short term mine scheduling aims to provide a constant amount of material to the milling facility. Among the available approaches, mathematical modeling is reliable in determining an optimum solution. Cut and fill mining is conducted in mineral reserves with weak surroundings. In this paper, a new mathematical model is introduced to production scheduling of drift and fill mining method while the special constraints of cut and fill mining is considered. The model is capable to consider mining operation in several levels. The model is applied for stope sequencing in Anguran mining project. The data from the +2721, +2733 and +2737 levels are used for production scheduling and stope sequencing. The Anguran underground project is a cut and fill mining project. In this mine the levels are separated into 2 northern and southern panels. The results show that simultaneous mining of +2721 and +2737 levels is capable of reaching the predetermined production level with a maximum deviation of 2.4%.
