| 中文摘要: |
| 大别山区地表水资源相对较为贫乏,地层以元古界变质岩为主,受地下含水介质的影响,地下水资源也很缺乏。本文以1∶5万水文地质调查为基础,结合大别山变质岩山区特殊地形地貌及水文地质条件,确定了汪家湾找水靶区。采用音频大地电磁法、高密度电阻率法、电阻率联合剖面法、激发极化法四种方法联合勘探,确定了井位,并进行了探采结合孔的验证。通过钻探结果对比了这四种方法在变质岩山区找水应用中的优缺点,并建立了“面-线-点”的找水模式,为今后在该类变质岩贫水区的找水工作提供了技术借鉴与参考。 |
| 英文摘要: |
| The surface water resources in Ta-pieh mountain area are relatively poor,and the strata are mainly proterozoic metamorphic rocks.Due to the influence of underground water-bearing medium,the groundwater resources are also scarce.Based on 1∶50,000 hydrogeological survey and combined with special topography and hydrogeological conditions in the dabieshan metamorphic mountains,this paper determines the Wangjiawan water prospecting target area.Four joint exploration methods,namely audio magnetomagnetics,high density resistivity method,resistivity joint profile method and induced polarization method,were used to determine the well location and verify the combination of exploration and production holes.Through drilling results,the advantages and disadvantages of these four methods in water prospecting in metamorphic mountainous areas are compared,and the “surface-line-point” water prospecting model is established,which provides technical reference and reference for water prospecting in the poor water area of metamorphic rocks in the future. |
