| 摘 要： | 大同市地下水开采的有关资料表明,自1981年以来大同市地下水开始超采,致使大同市地下水各降落漏斗已逐渐靠拢或合并,已经形成了一占据大同大半市区的降落漏斗。通过对大同市各地下水取水点超采量的变化、地面沉降的发生时间与相应位置、地裂缝产生的规律、地质构造的区域背景资料的详细对比与分析,说明了地下水严重超采是导致大同市地面沉降与地裂缝产生的直接诱因。

| Abstract: | Related data of ground water mining in urban Datong demonstrated that extraordinary mining of ground water since 1981,made the various drawdown cones gradually closed together and even merged and formed a large drawdown cone with an area of more than half of urban Datong.After detailed contrasting and analyzing each ground water well extraordinary min-ing changes,surface subsidence happening time and relevant location,ground fissure formation orderliness,regional geo-logical structure setting,explained the direct inducement of surface subsidence and ground fissure formation is severe extraor-dinary mining of ground water. |
