| 中文摘要: |
| 莱芜铁矿田中,一般情况下地表水、第四系潜水与岩溶水无水力联系,地表无塌陷产生,只有在新构造断裂发育的地段,才有可能产生岩溶地面塌陷。而在这些地段,灰岩顶部岩溶裂隙发育的程度,覆盖层结构,地表水、第四系潜水与岩溶水的水力联系均有新构造断裂控制,而这几方面正是岩溶地面塌陷产生的必要条件,所以,莱芜铁矿田中的岩溶地面塌陷由新构造断裂控制。 |
| 英文摘要: |
| In generall surface water, Quaternary ground water and karst water are not hydraulically linked with each. Other in Laiwu iron ore field. However karst sinking at surface tokes place in places where neotectonic faults are developed. In such areas karst development at top of limestone, structure of the burden sediments hydraulic linkage of surfac wafer, Quaternary ground water and karst water are controled by Neotectonics and they are the prerequisite for surface karst sinking. Thus surface karst sinking in Laiwu iron ore field is controled by Neotectonics. |
