Optimization of mine mass cargo flows during fan mining of the field

Background. A method is presented for analytically determining the optimal distribution of cargo flows during rock mass transportation by road, factoring in the given transportation distance. The key parameter for optimization is transport work, defined as the product of the volume of the rock mass and the transportation distance. This method involves exploring various cargo flow scenarios when developing wedge-shaped blocks, determining the transport work and optimizing it based on well-known mathematical methods. For this purpose, the extremum of the function is determined. As an alternative (additional), you can use the graphical method. Aim. Reduce transportation costs for rock mass removal by optimizing road transport cargo flows. Methods. Analytical methods, mathematical approaches to finding the extremum, methods of mathematical statistics. Results. A methodology was developed to optimize rock mass cargo flows during the fan-shaped development of a field. Conclusion. This study provides a foundation for determining the optimal distribution of rock cargo flows in fan-shaped field development. The proposed optimization technique can be used in other development systems with multiple transportation routes from one ledge.
