水文地质调查与物探在岩浆岩地区找水中的应用——以田黄镇律庄村地下水勘查为例

Application of hydro-geological survey and geophysical exploration to water search in magmatic areas——Taking the groundwater exploration of Lvzhuang village in Tianhuang town as an example

田黄镇地处邹东低山丘陵区,岩浆岩集中连片发育,受地形地貌及地质条件制约,地下水资源较为匮乏,制约着经济社会发展,地方找水需求极为迫切。本文综合研究区地质构造背景、地下水的赋存特征,采用大比例尺水文地质调查和物探勘查相结合的方法,通过水文地质调查确定找水方向,划定物探靶区,再辅以物探方法加以验证,对物探异常进行充分解释判别后,最后进行钻探验证。结果表明:应用水文地质调查与物探方法准确探查到地下水富水区域,在严重缺水的岩浆岩丘陵山区找到了较好的地下水,解决了当地群众的生活用水问题。可为其他类似地区开展精准找水打井工作提供重要借鉴。

Tianhuang town is located in Zoudong low hills,magma rock concentrated and continuous development,by the topography and geological conditions,groundwater resources are relatively scarce,restricting economic and social development,the local water demand is extremely urgent.This paper synthesises the geological and tectonic background of the study area,the features of groundwater storage,and adopts the method of combining large-scale hydro-geological investigation and physical exploration survey,determining the direction of water search through hydro-geological investigation,delineating the target area of physical exploration,supplemented with physical exploration method to verify,and finally carrying out drilling to verify the anomalies after fully interpreting and judging the anomalies in the physical exploration.The results show:The application of hydro-geological investigation and physical prospecting methods accurately probed the groundwater-rich areas and found better groundwater in the seriously water-scarce magma rocky hilly mountainous areas,solving the problem of living water for the local people.It can provide an important reference for other similar areas to carry out accurate water search and drilling work.
