山东省苍山县沟西西官庄铁矿沟西矿区水文地质特征及涌水量预测

Hydrogeological Characteristics and Prediction of Water Inflow of West Mine Area in GouxiXiguanzhuang Iron Deposit in Cangshan County of Shandong Province

摘要:

山东省苍山县沟西西官庄地区赋存有隐伏的鞍山式低品位铁矿，矿区水文地质条件属于中等型。对勘探施工的51个地质孔全部进行了简易水文地质编录，9个水文地质孔进行分层抽水试验,查明了铁矿矿区水文地质条件，对矿床充水因素进行了分析，确定水文地质单元边界条件模型，采用承压—无压完整式巷道双边进水水平坑道计算公式，对坑道各水平涌水量预测。预测结果与相邻水文地质条件相似的开采矿山涌水量分析对比，基本与当地相邻矿山涌水量实际相符，能够为矿山开发利用提供地学依据。

Abstract:

Hidden Anshan type low grade iron deposit occurred in GouxiXiguanzhuang area of Cangshan county in Shandong province. Hydrogeological conditions in this area belong to middle type. 51 geological exploration and construction holes have been processed, and stratified pumping test of 9 hydrogeological holes have been carried out, hydrogeological conditions of iron deposit have been identified, water filling factors have been analyzed, and hydrogeological units boundary condition model has been determined. By using pressure——no pressure complete roadway level of bilateral water tunnel formula, water inflow to the tunnel level has been predicated. Comparing and analyzing predication results with adjacent hydrogeological conditions with similar exploitation water inflow, it is regarded that water inflows of adjacent mines can match the actual conditions. It can provide scientific basis for mine development and utilization.
