黄河流域煤矿生态修复技术研究现状及展望

    Research status and prospect of ecological restoration technology for coal mines in the Yellow River basin

    • 摘要: 黄河流域是我国重要的能源流域,大规模煤炭开采严重破坏了当地生态环境,明确流域内生态环境破坏现状进行分区修复是保障黄河流域的生态安全和煤炭可持续开采、实现流域高质量发展的重要举措。本文通过搜集国内学者对黄河流域生态修复开展的研究,分析各区域实现生态修复已掌握的治理技术和开展的工程实践。结果表明:高寒区煤矿区生态修复是以恢复地表植被、保护冻土为目的进行人工建植和土壤修复技术的研究;黄土区和风沙区是以保护水资源为目的进行沉陷区治理和保水采煤技术的探索;冲积平原区是以恢复耕地和建设用地为主开展土壤重构、采空区利用和湿地构建的工程实践。最终明确了黄河流域煤矿区在治理技术、理念、高新技术应用以及多学科融合等方面存在的不足之处,并针对充实理论研究、加快技术研发、推广优秀工程实践等方面提出展望。

       

      Abstract: The Yellow River basin is an important energy basin in China.Large scale coal mining has seriously damaged the local ecological environment.In this regard, it is an important measure to make clear the current situation of ecological environment damage in the Yellow River basin and carry out regional implementation to ensure the ecological security and sustainable coal mining in the Yellow River basin and realize the high-quality development of the basin.Based on the research on ecological restoration of the Yellow River basin by domestic scholars, this paper analyzes the control technology and engineering practice of ecological restoration in various regions.The results show that in order to restore vegetation and protect frozen soil, artificial planting and soil restoration technology are studied in alpine region; in loess area and sandstorm area, subsidence area is treated and protected for the purpose of protecting water resources.In the alluvial plain area, soil reconstruction, goaf utilization and wetland construction are mainly carried out.Finally, the shortcomings of Yellow River basin coal mining area in governance technology, concept, high-tech application and multidisciplinary integration are clarified.
