平阴县洪范池铁矿开采对附近泉水的影响

洪范池铁矿体赋存于太古宙泰山岩群山草峪组，矿体周围泉水众多，论证矿床开采疏排水能否对泉水产生影响具有重要意义。研究分析表明，朱砂洞组含水层及山草峪组风氧化带裂隙水是矿床充水的直接充水水源，矿床充水水文地质条件属简单类型。泉水出露于寒武纪张夏组含水层中，并且与山草峪组含水层间无水力联系。若张夏组含水层不与采区沟通，矿山生产疏排水不会对泉水产生明显的影响。

Influence to the Surrounding Springs Due to Exploitation of Hongfanchi Iron Deposit in Pingyin County

Hongfanchi magnetite deposit locates in Shancaoyu formation of Neoarchean Taishan group. There are many springs around the orebodies. Thus, it has great significance to study the effect on springs of mining water. As showed by the study result, water-bearing layers of Zhushadong formation and fissured water in efflorescent oxygenized belts of Shancaoyu formation are direct water sources. The hydrogeological condition of deposit water filling type is simple. The spring water exposed in water bearing layers of Cambrian Zhangxia formation and has no hydraulic interaction with water bearing layers of Shancaoyu formation. If water bearing layers of Zhangxia formation do not communicate with mining area, it has no obvious influence to spring water.
