山东张宝庄铁矿水文地质特征研究

Study on Hydrogeological Characteristics of Zhangbaozhuang Iron Deposit in Shandong Province

摘要:

张宝庄铁矿矿床位于当地侵蚀基准面以下，呈似层状，倾角多在45°以上，埋深20～888m。对矿区3个主要含水层及其之间的水力联系进行分析，这3个含水层分别为第四纪全新世冲洪积孔隙水含水层、基岩风化裂隙水含水层和泰山岩群变质岩构造裂隙水含水层，各含水层之间水力联系较弱。另外还研究了矿床充水因素、预测矿床正常涌水量和最大涌水量，在此基础上划分该矿区水文地质条件为中等类型。

Abstract:

Zhangbaozhuang iron deposit locates below the local base level of erosion with bedded type. Its dips are almost more than 45 °, and the depth is 20~888m. Through study on three main water bearing layers and their hydraulic connection in this area, it is regarded that these three water bearing layers were Holocene pore alluvial water bearing layer in Quaternary, bedrock weathering fissure water bearing layer and the tectonic fracture water bearing layer in metamorphic rocks in Taishan group. Hydraulic connection among these water bearing layers is very weak. Water filling factors of this deposits have been studied, and the medium type of normal water inflow and water inflow have been predicated as well. On these basis, hydrogeological conditions of this deposit has been classified into medium type.
