| 中文摘要: |
| 抽水试验一直是矿山勘查和开采过程中重要的水文地质参数获取方式,相对于稳定流抽水试验,非稳定流抽水试验具有试验时间较短、参数获取较多,并能直接反映地下水的补给和径流条件。通过对内蒙古曹四夭钼矿非稳定流抽水试验中观测孔的时间—降深双对数曲线和时间-降深单对数曲线形态的分析,查明了该区地下水补给条件差,获得了必要的水文地质参数。对今后指该类矿区开展水文地质工作具有借鉴意义。 |
| 英文摘要: |
| Pumping test is the most important way to obtain the hydrogeological parameter in the process of mining prospection and extraction. In comparison with steady flow pumping test,unsteady flow pumping tests take less time,obtain more parameter and can reflect the groundwater recharge and runoff environment directly. In unsteady pumping test in molybdenum ore areas of Cao Siyao,according to hole observation time—drawdown double logarithmic curve and time—drawdown single logarithmic curve analyses,it was proved that the groundwater recharge environment is poor in this area,and also the hydrogeological parameter was obtained. The results are very useful and instructive for the later hydrogeology work in this area. |
