摘要: 通过理论分析开采沉陷在地表所形成的连续的地表移动变形(下沉、倾斜、曲率、水平移动、水平变形等)或非连续变形(裂缝及台阶、塌陷坑)对耕地的影响,提出了以耕地灌溉的允许坡度、地下水位、积水、非连续变形作为开采沉陷对耕地损害的评定指标,为进一步研究矿区耕地的可持续发展提供基础。

Abstract: The impact of the continuous ground surface displacement and deformation (subsidence, curvature, horizontal displacement or horizontal deformation) or discontinuous deformation (crack, step or pit) induced by mining-caused subsidence on cultivated land is investigated through theoretical analysis. It is proposed to use the allowable slope for land irrigation, underground water table, accumulated water and discontinuous deformation as the indexes for assessing the damage of mining subsidence on cultivated land, thus providing a basis for the research on the sustainable development of the cultivated land in mine area.

Key words: Mining subsidence, Cultivated land, Damage index
