Abstract: Yunnan Province, as a major province of metallic mineral resources in China, ranks among the top in the country in terms of reserves of tin, copper, lead-zinc, and other metals. While the mining of metal mines has driven economic development, it has also triggered severe environmental problems, including soil erosion and geological disasters, soil and water degradation caused by heavy metal pollution, and air pollution from dust and exhaust emissions. How to coordinate mining with environmental protection has become a key challenge for regional development. This paper aims to systematically analyze the environmental problems of metal mine mining in Yunnan Province, trace the sources of pollution, draw on advanced domestic and international mining and ecological restoration experiences, and propose suitable production technologies and environmental protection strategies in combination with geological conditions in Yunnan Province. By analyzing the current situation of metal mine mining in Yunnan Province and combining it with typical cases, the study examines the differentiated environmental impacts of mining. It compares domestic and international technical practices to summarize transferable environmental protection technology pathways and proposes solutions from three aspects: technological upgrading, regulatory optimization, and policy incentives. The study finds that the environmental problems of Yunnan Province’s metal mines stem from outdated mining technologies, weak environmental awareness, and loopholes in the regulatory system. It is recommended to promote technologies such as backfill mining and in-situ leaching, strengthen corporate environmental responsibility systems, establish a multi-department collaborative regulatory mechanism, and guide industrial upgrading through tax incentives and ecological compensation policies to achieve a win-win situation between resource development and ecological protection.
