【摘要】：以兖州矿区为研究对象,选取8个样本矿点,采用理论分析法和专家咨询法,初步确定出14个土地破坏的一般影响因子;利用SPSS软件对因子进行相关分析,降低因子间相关性,消除重复信息,筛选出10个一般影响因子;采用地表下沉值作为衡量土地破坏程度的指标,分析其与10个因子的关联程度,最终确定可采煤层平均总厚、深厚比、地下水埋深、基岩厚度、宽深比、松散层厚度为兖州矿区土地破坏的主导影响因子,并分析其作用机理。为后续的土地破坏程度评价及复垦方案制定等奠定了基础,同时为其他类型矿区土地破坏主导影响因子的筛选确定提供借鉴。
[Abstract]:Taking Yanzhou mining area as the research object, selecting 8 samples, using theoretical analysis method and expert consultation method, the general influencing factors of 14 land damage were preliminarily determined, and the correlation analysis of the factors was carried out by using SPSS software to reduce the correlation between the factors. Eliminate the repeated information, screen out 10 general influence factors, adopt the surface subsidence value as the index to measure the damage degree of the land, analyze its correlation degree with the 10 factors, and finally determine the average total thickness, depth ratio, groundwater depth of the mineable coal seam. The thickness of bedrock, the ratio of width to depth, and the thickness of loose layer are the main influencing factors of land destruction in Yanzhou mining area, and the mechanism of action is analyzed. It lays a foundation for the subsequent evaluation of the degree of land destruction and the establishment of reclamation schemes, and provides a reference for the selection and determination of dominant factors of land destruction in other types of mining areas.
