民进山西省委会提案建议：加快山西省煤矸石资源化利用

Core Viewpoint - The increasing stockpile of coal gangue in Shanxi Province, exceeding 1 billion tons and growing at nearly 100 million tons annually, poses significant environmental challenges, necessitating accelerated resource utilization strategies to support the province's coal industry and promote green transformation [1]. Group 1: Resource Utilization Strategies - The proposal suggests constructing a quality and grade-based utilization system for coal gangue, including research on its resource and environmental properties, establishing classification standards, and creating a comprehensive utilization plan [2]. - Coal gangue can be categorized based on carbon content and calorific value into four types, with low carbon content suitable for backfilling and high carbon content usable as fuel for power generation and heating [2]. - Existing coal gangue stockpiles require risk assessments before implementing ecological restoration or pollution control measures, with cost-effective and environmentally friendly methods prioritized for large-scale utilization [2]. Group 2: Industrial Chain Development - The establishment of a complete industrial chain is recommended, focusing on secondary sorting, power generation, high-performance building materials, and high-value chemical products, creating a closed-loop system from coal to agricultural applications [3]. - Emphasis is placed on typical demonstration projects that can provide replicable experiences, such as comprehensive waste utilization enterprises and intelligent sorting systems [3]. - Collaboration between industry, academia, and research institutions is essential to advance technology and reduce the gap with international standards, enhancing the economic benefits of coal gangue utilization [3]. Group 3: Policy Support and Information Integration - The proposal calls for improved fiscal, tax, and pricing incentives, including VAT exemptions for coal gangue power plants and funding support for circular economy projects [3]. - Establishing a comprehensive information network for coal gangue utilization is crucial, integrating data and employing AI technology to develop tailored utilization strategies [3]. - Collaborative efforts among government, universities, and enterprises are necessary to ensure effective implementation of classification management policies and technical pilot demonstrations, promoting sustainable development in Shanxi's coal industry [3].
