Abstract

Problem Statement (Relevance): Almost all of the copper-pyrite deposits found in the Southern Urals come in clusters, which are closely spaced clusters. The current practice is to develop such fields as separate deposits with no regard to the other fields within the cluster. However, this leads to increased capital investment related to the need to build another concentrator plant, increased ore transportation costs, etc., which eventually affects the overall cost-effectiveness of the mining operations. With the help of a feasibility study looking at the capacity of the mining system and the order in which the fields of a cluster should go in operation, as well as by choosing the best location for the concentrator plant, one can reach better performance indicators. Objectives: This research aims to provide substantiation for the operating parameters of the mining system to be used for the development of a cluster of closely spaced copper-pyrite deposits. Methods Applied: The methods applied include: Analysis – when looking at the designing practices used in the mining of copper-pyrite deposits; Options - when deciding on the opening method; Analogies - when justifying the choice of machinery; Reasoning - when developing one’s mining strategy for working a copper-pyrite cluster; Statistical processing of the projected costs related to the development of a copper-pyrite cluster; Analytical calculations; Feasibility study. Originality: Relationships have been established on how the location of the concentrator plant and the cluster development sequence can be determined by the asset value and the spacing between the fields. Findings: With the help of the relationships established one can choose, at the design stage, the most cost-effective mining strategy and reduce the ore transportation costs and the capital investment required for the construction of the site and the concentrator plant. Practical Relevance: This study helped the authors come up with a method for estimating the technical and economic parameters of mining systems used for the development of copper-pyrite clusters.
