| 摘 要： | 广西某铅锌矿矿区经过40多年的开采,昔日矿山良好的生态环境遭到严重破坏,矿区岩溶地表塌陷严重.从岩溶发育的地质环境、岩溶发育特征、塌陷概化模型、塌陷形成阶段等方面对该矿区岩溶塌陷的成因进行分析,表明该矿区因采矿大量抽排地下水,导致地表塌陷.

| Abstract: | A lead-zinc mining area locates in Rong＇an County,Liuzhou City,Guangxi.Through over 40 year＇s production,the ecological environment that had been fine is damaged seriously with severe karst ground collapse in this area.From the aspects of geological environment and characteristics of the karst development,conceptive model for the collapse,collapse formation stages,the genesis of karst collapse in this mining area was analyzed.The result shows that such collapse is caused by large amount of groundwater pumping therein for mining. |

| Keywords: | Karst ground collapse development characteristics conceptive model collapse formation stages groundwater pumping |
