This article investigates the phenomenon of mining-induced displacement and resettlement (MIDR) in post-mining cities, specifically focusing on Most City in the Czech Republic. Post-mining cities often face challenges associated with population decline, ageing infrastructure, and a lack of economic opportunities. To address these challenges, some cities have implemented urban relocation programs to consolidate populations and resources in more sustainable locations. However, the effectiveness of such programs needs to be better understood. This article presents the case study of Most City to explore the dynamics of MIDR of post-mining cities. Drawing on interviews with city officials, residents, and experts, as well as a review of relevant literature, the article identifies the key drivers and challenges of MIDR in the context of Most City. The paper also evaluates the outcomes of the relocation program in terms of social, economic, and environmental sustainability. Ultimately, this article discusses that MIDR can be a viable strategy for post-mining cities, provided that it is implemented in a manner that caters to the specific needs and challenges of each city, with the aid of digital technology, such as artificial intelligence (AI).
