基于剩余变形的采煤沉陷损毁土地动态复垦研究

Dynamic Reclamation for Damaged Land Based on Residual Deformation of Coal Mining Subsidence

在分析当前矿区土地复垦工作的基础上,以开采沉陷动态预计理论为指导,将地面治理和地下开采有机结合,构建了基于开采进度的地表剩余变形动态演化模型,结合具体案例,探讨了根据剩余变形选择动态复垦措施及时机的方法,通过对比分析,该方法有助于复垦工作的早期介入,减少土地荒芜时间,预防后续变形对已实施治理措施的影响。

Based on the analysis of current land reclamation work in the mining area of China,with the guide of dynamic theory of mining subsidence,a model for calculating the ground residual deformation with mining progress was constructed to organically combine the ground treatment and the underground mining. Then with a specific case,land reclamation measures and times was discussed based on residual deformation. Through comparison and analysis, this method could help to choose reasonable reclamation time,and reduce land waste time,and prevent the influence of subsequent deformation on the implemented reclamation work.
