Technical-economic analysis of variants of a micro location for the DTO crushing plant of the DTO system and connecting conveyor T1 at the open pit Potrlica, Pljevlja

Abstract

The Additional Mining Design for coal exploitation at the open pit "Potrlica" - Pljevlja for the period 2020 - 2025, has defined the exploitation system important parameters and development of the open pit. Among others, for the first half of 2022, it is planned to move the crushing plant to a new position, in a direction of the excavation front. Generally, the new position of the crushing plant has been verified within several project and study documents. Nevertheless, there is a need for precise definition of the crushing plant positions and conveyors within the DTO system in order to the create favorable and safe working conditions for mechanization on the loading plateau of the crusher, to provide a more favorable position of the crusher with the aim of easier plateau drainage and a more convenient approach to the crusher for easier maintenance, and to minimize the costs of relocation to a new position while respecting the projected dynamics of relocation works. In order to ensure the fulfillment of the set goals, a techno-economic analysis of the variants of a micro location of the crushing plant at this open pit was performed with an overview given in this paper.
