豫西缺水山区找水方法探讨

To explore the methods in dry mountainous areas

渑池县作为较典型的豫西缺水山丘区之一,地下水形成自然条件差,水文地质条件复杂,含水层富水性弱,开采难度大,人畜饮水困难。此种背景条件下,河南省地矿局第五地质勘查院开展了"渑池县严重缺水山区人畜饮用水水源地调查",通过收集析已有资料,研究缺水山区的地层结构特征、控水储水构造、地下水赋存、分布、循环演变规律;进行找水靶区的调研论证,并在缺水山区施工供水示范井。本文通过缺水山区找水方法步骤进行初步探讨,以调查分析研究、物探勘察解读等为手段,运用"以含水层为条件,地质构造为基础,地下水流运动规律为主导的储水构造三位一体找水模式"为指导,作为缺水山区找水的方法步骤,以此为开展省内缺水山区找水工作提供借鉴和参考。

Mianchi County as a typical Western Henan dry hills area of groundwater formation poor natural conditions,complex hydrogeological conditions,aquifer water weak,difficult to mine,people and livestock drinking water. Under this kind of background,bureau of Geology and mineral resources of Henan Province the fifth Geological Exploration Institute of＂a serious water shortage in Mianchi County mountain people and livestock drinking water sources survey was carried out,through the analysis of the existing data collection,mountains of water shortage of the structural features of strata,control water storage water structure,groundwater occurrence,distribution,circulation evolution; water prospecting target areas of research and demonstration,and in dry mountainous areas for water supply in construction of demonstration well. This paper through the steps of the mountain water geophysical methods of preliminary study,research,geophysical interpretation as a means to use ＂to aquifer condition,geological structure as the foundation,the law of motion of the underground water for water storage structure leading Trinity detection groundwater model as a guide,as the method and steps of mountain water for groundwater,taking the opportunity of development water exploration work in mountain areas in the water shortage in the province and provide the reference to investigate analysis.
