苍山县大青山铁矿矿床水文地质特征与涌水量预测

山东省苍山县大青山铁矿属隐伏的鞍山式低品位铁矿。该文分析了矿床的水文地质条件,阐述了矿体盖层、矿体围岩及顶底板水文地质特征。对研究区内勘探孔进行野外简易水文地质编录和水文地质钻孔分层抽水试验,获得了含水层厚度、影响半径、渗透系数等基础数据,采用“大井”涌水量计算法对矿体赋存各标高段进行涌水量预算,结果可为当地矿床开采技术条件提供技术指导,也为同类研究提供实例。

Hydrogeological Characteristics and Water Inflow Prediction of Daqing Iron Deposit in Cangshan County

Daqingshan iron deposit in Cangshan county of Shandong province belongs to Anshan type low grade iron deposit. In this paper, hydrogeological conditions of this deposit have been analyzed, the cover layers, country rocks of ore bodies and hydrogeological characteristics of top and bottom roofs. Simple field hydrological geological logging and hydrogeological drilling stratification pumping tests of exploration holes in this area have been carried out, and obtained basic datas of aquifer thickness, radius of influence and permeability coefficient. By using inflow calculation method of "large wells", water inflow amounts of each elevation sections have been predicated. The obtained results can not only provide technical guidance for local mining, but also provide an example for the similar research.
