摘要
为深入研究松散层、上覆基岩厚度、煤层厚度等因素对采空区地表塌陷的影响,以挖金湾矿8103、8105工作面为研究对象,根据工作面实际地质条件,利用灰色系统理论分析模型,得到各影响因子对地面塌陷破坏程度的权重,并借助ArcGIS软件可视化分析,建立未开采区域地表塌陷破坏程度的计算方法,结果表明:计算结果与实测数据基本相符,可为其他未开采区域地表塌陷破坏程度的预测提供参考。
In order to deeply study the influence mechanism of factors such as loose layer,thickness of overlying bedrock and thickness of coal seam on the surface subsidence of the goaf,No.8103 and 8105 Faces of Wajinwan Mine was taken as the research objects,according to the actual geological conditions of the working face,the grey system theoretical analysis model was used to obtain the weight of each influencing factor on the damage degree of ground subsidence,and a method for predicting the damage degree of ground subsidence in unmined areas was established by visual analysis of ArcGIS software.The results showed that the predicted results were basically consistent with the measured data,which was of great significance to prevent and avoid gob collapse,and to protect the surface ecological environment to the greatest extent.
