采煤沉陷区生态修复治理措施初探

Preliminary study on ecological restoration measures in coal mining subsidence area

为提高采煤沉陷区生态修复治理效果,探索行之有效的治理技术措施,以太原市万柏林区采煤沉陷区为研究对象,通过野外调查和物探勘查手段,查清研究区现生态环境问题。针对植被枯死、景观水塘漏水、道路损毁及广场地表开裂等生态环境问题分别提出了治理思路和治理措施,研究结果表明:1)采空区生态环境问题突出,综合治理前采空区至少要达到基本稳定状态;2)综合治理措施要与当地发展规划需求相结合,针对不同的生态环境问题,分别选取修复治理措施;3)从技术角度选取地基加固或柔性防水措施进行地面沉陷生态环境修复是可行的。研究成果可为采煤沉陷区综合治理与利用提供技术借鉴与实践应用参考。

In order to improve the effect of ecological restoration and governance in coal mining subsidence area,and explore effective governance technical measures,taking Wanbailin coal mining subsidence area of Taiyuan City as the research object,through field investigation and geophysical exploration means,the current ecological environment problems in the study area were found out.In view of the ecological environment problems such as vegetation withering,water leakage of landscape pond,road damage and square floor cracking,the treatment ideas and measures are put forward respectively,1)The ecological and environmental problems of the goaf are prominent,and the goaf should at least reach a basic stable state before comprehensive treatment;2)the comprehensive treatment measures should be combined with the local development planning needs,and the restoration and treatment measures should be selected according to different ecological and environmental problems;3)From the technical point of view,it is feasible to select foundation reinforcement or flexible waterproof measures to repair the ecological environment of ground subsidence.The research results can provide technical reference and practical application reference for comprehensive treatment and utilization of coal mining subsidence area.
