| 摘 要： | 开采沉陷对地表破坏规律的研究已取得了丰硕成果，但工采沉陷以耕地的破坏机理研究较少，通过对开采沉陷盆地土壤特性的动态监测，发现开采沉陷对土壤特性的影响有明显的规律性并且是导致耕地生产力下降的主要原因，土壤物理特性受沉陷影响较显，而化学特必除电导率外并不明显，开采沉陷对土壤特性的影响滞后于沉陷过程。’

| Abstract: | The research on the surface movement due to coal mining subsidence has got great achievements. But the mechanism of farmland damage has not been studied deeply. Based on the dynamic tests of soil properties in subsided land, we discover the distinct changing rule of soil properties affected by mining subsidence and think that the change of soil properties is the main reason of the degression of farmland productivity. Soil physical properties are sensitive to mining subsidence, but soil chemical properties are not sensitive exception of soil electrical conductivity. The impact of coal mining subsidence on soil properties of farmland usually happens after subsidence proceeding. |
