矿山涌水量预测探讨——以某铁矿为例

Discussion on Prediction of Mine Water Inflow-taking an Iron Ore as an Example

矿山涌水受到众多因素影响,其水量在各月份上分布及其不均,使得丰水期涌水量是枯水期的几十倍甚至上百倍。丰水期大量弃水直接排放至环境中,将对受纳水体造成影响。因此,探讨矿山开采不同时期、不同季节的涌水变化,矿山开采的同时保护水环境具有重要意义。本文以西藏某铁矿为例,选取大井法预测不同阶段矿山涌水的变化,以讨论整个矿山开采项目在不同的工程阶段对区域水环境的实质性影响。

Mine water inrush is affected by many factors. For one reason, the yield of the mine water is unequally distributed in every month, and the mine water during wet seasonsis several times than that during dry seasons. There is a large amount of mine water discharged directly into surroundings during the wet seasons, which could have influence on the receiving water. Thus, it is significantly meaningful to investigate the change of Mine water inrush during different periods and seasons, meanwhile, it is also important to protect environment when mining. In this paper, an iron mine in Tibet is taken as an example, and it attempts to predict the change of mine water inrush during different periods and seasons by using ground water dynamics method (big well method), and to discuss the influence of mine on the regional water environment in different construction stages.
