The practice and understanding of the electrical exploration to seek groundwater in limestone area invaded by igneous rocks

  • 摘要: 太行山前的大多数石灰岩受火成岩的侵入,造成这些地区的地下水分布极不均匀,施工成井率很低。为了合理有效地开发地下水资源,在工作区进行水文地质调查的基础上,垂直于主构造线方向布置了3条电阻率法勘探剖面线,运用对称四极电阻率测深法,分别测量了视电阻率值。通过绘制视电阻率等值线断面图,定性和定量解释火成岩侵入的石灰岩地区地下富水带在视电阻率等值线图上的表现形态,准确的确定了井位。通过钻探工程验证,水井的出水量较为理想,与物探推断分析得出来的结论吻合良好。在这类地区开展电法找水,研究水文地质条件是基础,野外工作布置要灵活,深刻分析视电阻率等值线的异常形态是关键。
    Abstract: The groundwater distribution is uneven and water resources are very lack in the Taihang Mountain area with limestone invaded by igneous rocks.The success ratio is low in drilling well.In order to reasonably develop groundwater resource,the three electrical exploration lines were arranged in the direction perpendicular to main geology structures based on the hydrogeological investigation in the working site.The apparent resistivity values were observed by means of the resistivity sounding with the symmetric quadrupole along the lines.Through draw-ing the iso-apparent resistivity sectional map,the anomaly modality of groundwater-enriched zones was analyzed and interpreted on the map.Drafted well position was selected.Drilling engineering showed that the well yield was large and geophysical exploration method was effective.It is pointed out that the investigation of hydrogeology is foundation,working arrangement should be flexible and deepened analysis and interpretation of anomaly modality are key for seeking groundwater in this kind of area.
