A new model for the economic impact assessment of large-scale and deep open-pit mines

Abstract

This study focuses on examining economic impacts associated with deep and large-scale open-pit mining operations, which are often neglected in environmental impact assessments. Using Z-Fuzzy Delphi AHP and scenario-based techniques, 28 economic impacts were classified into seven categories and evaluated for the Sungun Copper mine in northwest Iran. Results indicated that socioeconomic factors had the highest weight (21.4%), while monetary factors had the lowest weight (7.5%). The economic sustainability score for the SCM was calculated to be 2.111, indicating poor economic performance. This research highlights the importance of considering economic impacts in mining operations for sustainable development.
