摘　　要：建立了基于裂缝法线方向上土壤物理性状变化趋势的地表采动裂缝对其周围土壤扰动范围的预计模型,为矿区地表采动裂缝治理、村矿矛盾裁决、土地复垦和生态修复等提供技术支持。利用现场实测数据和建立的模型得到了垂直于裂缝方向的土壤气相率变化模型以及裂缝宽度与土壤扰动范围之间的关系模型。测量数据验证表明,模型预计结果和实际结果相对误差为1.72%。A prediction model of disturbance range of ground mining cracks is established based on the soil physical properties variation around cracks in normal direction. It provides tech- nical support for ground mining cracks treatment, miner-villager conflict adjudication, land reclamation and ecological restoration. The model of air ratio variation perpendicular to crack line and the model of width of ground crack and disturbance range are obtained by regression test on field test data. Field measurement results show that the relative error is 1.72%.
