中文摘要:

为应对宜溧地区露天灰岩矿山的地质环境问题与恢复治理需求，本研究选取双友矿山为典型案例。基于无人机倾斜摄影技术获取高分辨率影像，构建矿区三维实景模型；综合运用 ArcGIS空间分析与 FLAC3D数值模拟方法，系统评估了矿区地形特征(坡度、坡高)、边坡稳定性、危岩体分布及边坡类型。在此基础上，结合专家访谈法构建矿山环境恢复治理分区综合评价模型，并利用评价因子数据对治理分区进行了量化评价。结果表明:治理分区中自然修复区、辅助再生区和生态重建区，面积占比分别为 44. 84%、37. 63%和 17. 53%。据此提出分区治理关键措施:自然修复区以消除生态胁迫因子(封闭场地、拆除设施)为主，依赖生态系统自我修复；辅助再生区需实施坡面修整、土壤改良与截排水等人工辅助措施改善生态系统恢复条件；生态重建区则需通过工程措施消除矿山地质环境隐患，并实施地貌重塑、土壤重构与植被重建以加速生态系统恢复。研究成果为宜溧地区类似露天灰岩矿山的系统性环境治理提供了科学依据和技术参考。

英文摘要:

To address the geological environmental challenges and rehabilitation needs of open-pit limestone mines in the Yili region，this study utilizes Shuangyou Mine as a representative case. High-resolution imagery was acquired using UAV oblique photogrammetry to construct a 3D real-scene model of the mining area. A comprehensive assessment of topographic features(slope gradient，slope height)， slope stability，distribution of unstable rock masses，and slope types was systematically conducted using integrated ArcGIS spatial analysis and FLAC3D numerical simulation methods. Subsequently，a comprehensive evaluation model for mine environmentalrehabilitation zoning was developed by incorporating expert interviews，and quantitative assessment of rehabilita.tion zones was performed using evaluation factor data. The result shows that the natural restoration zone，assisted regeneration zone，and ecological reconstruction zone accounted for 44. 84%，37. 63%，and 17. 53% of the total area in the governance zoning. Under the zoning framework，key governance measures are proposed accordingly: In the natural restoration zone，primary focus is placed on eliminating ecological stress factors(e. g.，site closure and structure dismantling)to rely on ecosystem self-restoration；the assisted regeneration zone requires artificial interventions such as slope grading，soil improvement，and interception-drainage systems to enhance ecosystem recovery conditions；while the ecological reconstruction zone necessitates engineering measures to mitigate mining geo-environmental hazards，coupled with landform reshaping，soil reconstruction，and revegetation to accelerate ecosystem restoration. This research provides a scientific basis and technical reference for systematic environmental management of similar open-pit limestone mines in the Yili region.
