| 中文摘要: |
| 受经济、交通、技术等因素限制，西部干旱区风化煤大量堆积，严重破坏矿区脆弱的生态环境；缺乏适配的指标体系也在很大程度上制约了风化煤的资源化利用。基于此，本研究从风化煤的物理、化学、环境影响及施工性能等4个维度出发，系统构建风化煤资源化利用评价指标体系，并采用层次分析法（AHP）对风化煤资源化利用途径开展全面、准确、系统的评价。权重分析结果表明，影响风化煤资源化利用的准则层权重依次为化学性能指标（0.42）、施工性能指标（0.27）、环境影响指标（0.19）和物理性能指标（0.12）；其中，化学性能准则层下腐殖酸含量、有机质含量的指标权重分别位列第1位、第3位，说明化学性能对风化煤资源化利用起到决定性作用。此外，施工性能准则层的安全性指标权重排名第2，可见在风化煤工程应用阶段，既要兼顾风化煤的市场前景与经济效益，也要保障作业人员人身安全。最后选取新疆某露天煤矿风化煤开展实证分析，结果显示：除物理性能维度存在粒径偏大问题外，该露天矿风化煤资源化回用潜力突出，最优利用方向为土壤改良剂、肥料、生物材料等。本次资源化利用评价体系的搭建，可为风化煤清洁生产推进、煤炭行业可持续发展落地提供理论依据与方法参考。 |

| Due to constraints in economic development, transportation infrastructure, and technical conditions, large quantities of weathered coal have accumulated in western arid regions, causing severe damage to the already fragile ecological environment of local mining areas. At the same time, the lack of a suitable indicator system seriously restricts the resource utilization of weathered coal. Based on this context, the research proposes an innovative approach to systematically construct an evaluation index system for the resource utilization of weathered coal from four dimensions: physical, chemical, environmental impact, and construction performance. The Analytic Hierarchy Process (AHP) is employed to comprehensively, accurately, and systematically evaluate the pathways for the resource utilization of weathered coal. The results of the weight analysis indicate that the weights of the criteria affecting the resource utilization of weathered coal, in order, are chemical performance indicators (0.42), construction performance indicators (0.27), environmental impact indicators (0.19), and physical performance indicators (0.12). Among these, the weights of the humic acid content and organic matter content in the chemical performance criteria are ranked first and third, respectively, indicating that chemical performance plays a decisive role in the resource utilization of weathered coal. Additionally, the weight of the safety indicator in the construction performance criteria ranks second, highlighting the necessity of ensuring worker safety while guaranteeing the broad market prospects and profits of weathered coal during engineering applications. Finally, a practical case study is conducted using the weathered coal from an open-pit coal mine in Xinjiang. The results show that, apart from the larger particle size in the physical performance dimension, there is significant potential for the resource reuse of weathered coal in this open-pit mine, with the most promising utilization pathways being as soil amendments, fertilizers, and bioproducts. The establishment of this resource utilization evaluation system provides a reference for promoting clean production of weathered coal and sustainable development of the coal industry. |
