| 摘 要： | 调查了除州矿区几类非采矿沉陷造成的地裂缝的形态和环境，认为因构造，采矿，不均匀沉降产生的隐伏张裂隙是地裂缝的基础，干旱和超采浅层地下水使第四系浅部失水收缩激活和扩大了隐伏张裂隙，大雨后地裂缝显现，雨水沿裂隙面下渗时，发生潜蚀，刷大，惯通而造成塌陷。

| Abstract: | The research results show that basis of earth fissures is the potential weak faces caused by modern tectonism,old mine collapsed crack and ground differential subsidence.Shrinkage of upper Quaternary aquifer makes the weak faces renewed as over pumping.Earth fissure is the result of water sinking and under erosion along the fissure surface,after severe rain. |

| Keywords: | earth fissure underground water mining engineering structure |
