为了掌握开采沉陷所产生的附加坡度对耕地生产所造成的影响,基于开采沉陷理论和通用土壤流失方程,通过模拟实验和ABC分析方法,定量评价了开采沉陷附加坡度对耕地资源的影响。研究结果表明:开采沉陷附加坡度与深厚比呈幂函数关系,当深厚比小于60时,土地损毁程度严重;深厚比位于60~150之间时,土地损毁程度一般;深厚比大于150时,土地损毁程度较轻。研究结果可为矿区土地损毁评价提供理论依据。
In order to grasp the impact of additional slope on the cultivated land production, the effects of additional slope of mining subsidence on the cultivated land resources are quantitatively evaluated through simulation experiments and ABC analysis method based on mining subsidence theory and generalized soil loss equation. The results show that the additional slope of mining subsidence is a power function relationship with depth ratio. When the ratio of depth to thickness is less than 60, the degree of land damage is serious. When the ratio of depth to thickness is between 60 and 150, the degree of land damage is normal. When the ratio of depth and depth is greater than 150, Lesser extent of damage. The results can provide a theoretical basis for the evaluation of land damage in mining area.
