“大井法”在矿坑涌水量预测中的应用——以郎溪钒矿区为例

Application of “Large Diameter Well Method”in the Estimation of Mine Water Inflow——Taking Langxi Navajoite as an Example

矿井涌水量预测是矿床水文地质勘查的根本任务之一,"大井法"在预测矿井涌水量方面因其简单方便的特点而成为常用方法之一。通过"大井法"在具体工程实例中的应用分析,提出其在矿坑涌水量预测中的计算方法和存在问题,对矿坑涌水量预测的实际应用有一定的指导意义。

The estimation of mine water inflow is one of the fundamental missions in mine hydrogeological exploration. The＂large diameter well method＂to predict mine water inflow is often used in some exploration reports because of its simplicity.The article raised the calculational method and problems of＂ large diameter well method＂by it＇s analysis in project example.It can guide the estimation of mine water inflow.
