苍峄铁矿带苍山县沟西-西官庄矿区沟西矿段(凤凰山铁矿)主井井筒检查孔水文地质特征分析

苍峄铁矿带苍山县沟西-西官庄矿区沟西矿段,又称凤凰山铁矿,为隐伏的鞍山式低品位铁矿,矿区水文地质条件属于中等型。对施工的主井、副井、进风井、东风井和西风井井筒检查孔进行了水文地质编录和分层抽水试验,以主井井筒检查孔为例,划分了4层含水段,求得了各含水层的水文地质参数,对荒径涌水量进行了预测;基本查明了井筒检查孔的含水性等水文地质特征,确定了注浆段,为矿山立井防治水方案提供了设计依据。

Research on Daigu Landform in Shandong Province

Fenghuangshan iron deposit in Cangshan county is hidden low grade iron deposit, and hydrogeological condition belongs to medium type. Hydrogeological logging and pumping tests of inspection holes of main shafts, auxiliary shafts, intake shaft, Dongfeng well and Xifeng well bore wells have been carried out. Setting inspection holes of main shaft as an example, four oreCD*2]bearing layers have been dvided, the aquifer hydrogeological parameters have been obtained, and shortage of water inflow diameter has been predicted. Hydrogeological characteristics, such as aquosity has been identified basically, grouting segment has been determined. It will provide design basis for making water prevention programs mine shaft .
