Network model optimization of existing mining enterprises to sustain production capacity

The paper is devoted to the sustainability of the production capacities of mining enterprises when extracting minerals. The timely capacity restoration is the main problem for scientists dealing with sustainable development in mining construction. The paper presents the use of network planning and optimization methods of dynamic programming to solve problems of sustaining the existing capacities of mining enterprises. The proposed methods allow for the integrated use of network planning and dynamic programming to optimize the parameters of mining operations. A network model of the technological scheme of mining operations with optimal parameters is proposed. The necessity of timely restoration of capacities of mining enterprises with the use of network planning and mathematical programming methods in solving these problems is highlighted.
