| 摘 要： | 山东省济南市东郊某在建铁矿,于2009年7月产生了严重的地面塌陷。通过环境地质调查发现,该矿区地面塌陷并非通常所说的采空区塌陷,而是岩溶地面塌陷。该结论为矿山地面塌陷防治提供了依据,更重要的是否定了第四系厚度大(大于35m)不能产生岩溶地面塌陷的已有认识,并预示隐伏岩溶发育地区,随着上覆松散土体厚度的加大,一旦产生岩溶地面塌陷,其规模和危害也将随之增大。 |
| 关 键 词： | 铁矿 地面塌陷 成因判别 岩溶水排放 山东省济南市 |

| Abstract: | Severe land collapse happened in a constructing iron mine on July,2009,which is in eastern suburbs of Jinan City,Shandong Province.It is proved by environmental geological survey that the land collapse is not commonly referred as collapse of mined-out area,but karst collapse.The conclusion can provide basis for prevention and control of mine land collapse,and more importantly,it is negative for the existing theory that thick Quaternary（greater than 35m）can not produce Karst collapse,futhermore,it indicates that,in hidden karst area,with the increase of overlying loose soil thickness,once karst land collapse happens,its extent and damage will be even greater. |
| Keywords: | iron mine land collapse causes discrimination discharge of karst water Jinan City Shandong Province |
