黄陵矿区洛河组砂岩水文地质特征及水资源开发与保护

根据大量的供水勘察资料，从洛河组砂岩所处的区域构造位置、它的分布与厚度变化规律、孔隙裂隙特征、水力性质、动态变化、水质特征、环境水文地质条件诸方面进行了详细地论述；分析了洛河组砂岩地下水的补给、径流、排泄条件，指出洛河组砂岩分布面积广、厚度大，地下水丰富且水质良好，具备形成大型水源地的条件。同时分析了煤炭资源开发、人工开采、林业生产等可能对水源地造成不利影响的因素，提出了开发和保护水资源的建议和措施。

Hydrogeological features of sandstone in Luohe formation of Huangling mining area and exploitation and protection of water resources

Based on the large quantity of water- supply prospecting informations, reviewed in detail for sandstone of Luohe formation on its regional structural location, distribution and change law of thickness, features of pore and fracture, characteristics of waterpower, dynamic change, features of water quality, environmental hydrogeological conditions and so forth; and analysed the conditions of recharge, watershed, drain of groundwater in sandstone of Luohe formation; and indicated that sandstone of Luohe formation has wide area of distribution, large thickness, and there are abundant ground water and good water quality, so possess forming condition of large water supply. In the meantime analysed the factors which may be made unfavourable influences for water supply by exploitation of coal resources, artificial mining, forest production, etc., and provided some suggestions and measures on exploitation and protection of water resources.
