为了给煤矿沉陷耕地的复垦治理提供理论依据， 以兖州矿区为例， 对沉陷耕地不同下沉位置、不同土层的土壤进行了监测和分析， 揭示了开采沉陷对耕地土壤物理特性影响的空间变化规律． 结果表明， 开采沉陷显著影响耕地表层土壤的物理特性； 沉陷耕地上中坡土壤有砂质化的趋势， 而下坡和坡底则积聚了上中坡侵蚀下移的细颗粒土壤物质； 在土壤物理特性中， 受其影响最大的是土壤含水量， 其次是物理性砂粒含量， 再次是土壤容重和孔隙度．
In order to provide a theoretical basis for the reclamation and management of subsided cultivated land in the coal mine, taking Yanzhou Mining Area as an example, the soil in different subsidence positions and different soil layers of subsided cultivated land was monitored and analyzed, revealing the space affected by mining subsidence on the physical characteristics of cultivated land soils The law of change. The results show that the mining subsidence significantly affects the physical characteristics of the topsoil; Subsoil soil has the tendency of sandyification in the subsided cultivated land, while the downhill and bottom of the slope accumulate the fine granular soil material which descends on the upper and middle slope erosion; Among the physical characteristics, the soil moisture content is the most affected, followed by the physical sand content, again the soil bulk density and porosity.
