沂蒙缺水山区地下水赋存规律及找水定井范例

沂蒙山区是山东省重点贫困缺水地区,缺水区域分布较广,区内地质条件复杂,找水难度极大。通过综合分析区内气象水文、岩性特征、地质构造及地形地貌等地质因素,初步查明了不同地段含水层的结构和富水性;并结合水文地质调查、物探、钻探等综合勘探方法和手段,实施了探采结合孔8口,成功率100%,满足了区内约3万余人的饮用及300余亩土地灌溉用水需求,取得了良好的经济和社会效益。为我国北方严重缺水山区找寻地下水起到了宝贵的指导和示范作用。

Occurrence Regularity of Groundwater Exploration and Drilling Well Location in Water Deficient Area in Yimeng Mountain Area

Yimeng mountain area is water deficient area in Shandong province. Due to its complicated geological conditions, water exploration is very difficult in this area. Through analyzing meteorology and hydrology, lithological characteristics, geological structure and landform, structures and water abundance of aquifer in different sections have been primarily identified. Combining with comprehensive exploration methods, such as hydrogeological survey, geophysical prospecting and drilling, eight exploration and extraction holes have been successfully drilled which could meet not only the drinking need of 30000 residents, but also meet the irrigation demand of 300 mu land. Great economic and social benefit have been achieved. It will provide successful experiences for instructing further exploration of water in waterdeficient area.
