Core Points - The article highlights the significant issue of historical abandoned mines in China, with approximately 99,000 such mines and 420,000 hectares of land requiring remediation [1][5] - The Ministry of Ecology and Environment is set to introduce technical standards for investigating solid waste pollution in historical mining areas to enhance pollution prevention and ecological protection [1][2] Group 1: Current Situation - China has around 99,000 abandoned mines, including approximately 75,000 non-metallic mines, 11,700 metallic mines, and 12,300 energy mines [1] - The majority of these abandoned mines are small-scale, with 928,000 being small-sized and 62,000 being medium to large-sized [1] - The mining activities primarily utilize open-pit methods, contributing to significant land occupation and heavy metal pollution [1] Group 2: Regulatory Framework - The newly revised Mineral Resources Law includes a dedicated chapter on ecological restoration in mining areas, mandating local governments to organize remediation efforts when the responsible parties are untraceable [2] - The law emphasizes compliance with relevant regulations and technical standards for pollution control in mining areas [2] Group 3: Challenges in Waste Management - Historical solid waste in mining areas is characterized by its hidden nature, scattered distribution, and extensive range, making identification and assessment challenging [2][3] - The lack of specific technical standards for investigating historical mining waste and surrounding environmental media complicates remediation efforts [3] Group 4: Proposed Investigation Standards - The draft proposal outlines conditions under which historical mining waste may be deemed non-polluting, allowing for the exclusion of sampling investigations [4] - For waste that cannot be ruled out as polluting, sampling and analysis of surrounding environmental media will be required, utilizing advanced measurement techniques [4] Group 5: Remediation Strategies - The draft emphasizes a combination of natural recovery and artificial restoration for solid waste remediation, advocating for a systematic approach to pollution control [6]
