大宝山矿：从“生态疮疤”到“绿色明珠”的涅槃重生

Core Viewpoint - The article highlights the transformation of the Dabaoshan Mine from an environmentally damaged site due to unregulated mining activities to a model of ecological restoration and corporate responsibility, showcasing the commitment of state-owned enterprises to sustainable development and environmental stewardship [1][4][14]. Historical Context - Dabaoshan Mine has been a significant mineral resource base in South China since its establishment in 1958, contributing to the industrialization of the region [2][3]. - Unregulated mining activities, particularly rampant in the 1980s and 1990s, led to severe ecological damage, including soil erosion, acidification, and water pollution [2][3]. Ecological Challenges - At its peak, over 119 illegal mining operations and multiple processing plants severely degraded the geological environment, resulting in significant ecological issues such as soil and water contamination [3]. - The soil pH in the mining area dropped below 3, leading to heavy metal leaching and severe pollution of the nearby Hongshi River, which affected local communities [3]. Corporate Responsibility and Transformation - In response to the ecological crisis, Dabaoshan Mine took proactive measures to assume social responsibility, launching a comprehensive ecological restoration project with significant financial investment [4][11]. - From 2018 to 2021, the company invested approximately 100 million yuan in ecological restoration, covering an area of 90 hectares [4][11]. Innovative Restoration Techniques - The mine developed a novel "in-situ substrate improvement + direct vegetation" technology to address soil acidification and heavy metal pollution, collaborating with research institutions [5][11]. - A state-of-the-art wastewater treatment facility was established, capable of processing 96,000 cubic meters of acidic wastewater daily, achieving a heavy metal removal rate of 99% [5][7]. Successful Restoration Outcomes - The restoration efforts resulted in the successful rehabilitation of approximately 160 hectares of historical mining land, with a vegetation coverage rate exceeding 95% and soil pH levels rising above 6 [9][14]. - The Hongshi River has been transformed from a polluted waterway back to a clear river, enhancing the local ecosystem and community health [9][14]. Green Development and Future Outlook - Dabaoshan Mine is committed to ongoing ecological restoration and green transformation, planning to invest additional funds in environmental protection and technology development [14]. - The company aims to integrate advanced technologies such as AI and big data into its operations, striving to become a leading smart and green mining enterprise in China [14].
