Abstract: Exploitation of a man-made deposit formed by sections should be conducted with a minimum number of technological operations in order to improve the technical and economic performance of the enterprise involved in its development. This study describes methods for reducing the losses that arise during maintenance of a man-made deposit formed by sections, using a pull shovel or a walking dredge, the dependence of linear approximations of the faces of the walking dredge, dumpers installation diagram for loading while processing man-made raw materials within the sections. A mathematical model is provided that describes open-pit mining process flow during the development of a man-made deposit obtained by the method of linear programming. The research results allow involving man-made deposits with valuable minerals and at minimal cost.
