霍邱李楼铁矿水文地质特征及防治水措施

Huoqiu Lilou Iron Ore Hydrogeology Characteristics and Water Prevention and Control Measures

李楼铁矿是目前国内地下铁矿山中规模最大,水文地质条件较复杂的铁矿山。通过水文地质条件研究,认为基岩裂隙水是矿床的主要充水水源,节理裂隙是矿坑充水的主要通道,矿坑水很难预先疏干。采用比拟法预测了矿坑涌水量,结果表明矿坑深部的正常涌水量为10 062m^3/d,并提出了矿坑防治水技术措施。

Lilou Iron Ore is one of the domestic underground iron ore with largest scale and complicated hydrogeological conditions. Through the study of hydrogeological conditions study, we consider the bedrock fissure water is the main water source of water filling of deposit. The joint fissure is the main channel of water filling for the pit. The water in pit is hardly to be drained in advance. The paper adopts analogue method to predict the water inflow of the pit. The results show that the normal water inflow in the deep pit is 10 062m^3/d. And it puts forward the water prevention method for pit.
