摘要
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。
Based on the related theory of mining subsidence and universal soil loss equation （USLE）, the impact of addi- tional slope caused by mining subsidence on cultivated pro- duction was quantitatively evaluated by simulated experiment and ABC analysis method. Research results showed that the ratio of depth to thickness and subsidence additional slope were in power function correlation. Land destructed seriously When the ratio of depth to thickness was less than 60, land destruction was moderate when it was between 60 and 150, and land destruction was light when it was larger than 150. The study provided theoretical reference on destruction eval- uation of mining land.
