摘　　要：胡家庙子铁矿开采历史悠久,形成了3个露天采坑。随着采坑深度不断增大,目前坑底开采境界已无法满足矿山生产需求,需对露天采坑进行合并,以扩大开采范围。现状条件下,矿区水文地质勘查程度难以满足矿山建设及开采设计要求,为保障矿山可持续发展及矿床整体科学开发,需进一步查明矿床水文地质条件。通过水文地质调查、钻探及抽水试验等工作手段,详细查明了矿区各类岩层的分布和充水含水层的基本特征以及地下水补径排条件,充分分析矿床充水因素,并进行了矿坑涌水量预测,综合确定矿区勘查类型为第二类以裂隙含水层充水为主的矿床,水文地质条件复杂程度为中等。Hujiamiaozi Iron Mine has a long history of mining,three open-pit mining pits are formed.With the increasing depth of mining pit,the mining boundary of the bottom of the pit can not meet the pro⁃duction demand of the mine,so it is necessary to merge the open pit to expand the mining range.Under the current conditions,the degree of hydrogeological exploration in the mining area is difficult to meet the re⁃quirements of mine construction and mining design.In order to ensure the sustainable development of the mine and the overall scientific development of the deposit,it is necessary to further identify the hydrogeolog⁃ical conditions of the deposit.By means of hydrogeological survey,hydrogeological drilling and pumping test,the distribution of various rock layers in the mining area and the basic characteristics of water-filled aquifers as well as the conditions of groundwater rewatering and drainage were ascertained in detail.The wa⁃ter-filling factors of the deposit were fully analyzed,and the water inflow of the mine was predicted.The ex⁃ploration type of the mining area was comprehensively determined as the second type of deposit dominated by water-filled fissure aquifers.The hydrogeological conditions are moderately complex.
