云淫硫铁矿防洪排水工程,分为露天采场外围及废石场周围的截洪工程;采场上部的截洪工程及深部井巷排水工程。其中井巷自流排水系统,在化工矿山还是首次应用。实践表明,这种防洪排水工程是行之有效的,采场工作面经常保持良好的作业条件,地下水及暴雨迳流对采场边坡影响很小,矿山管理方便。 Yun Yin pyrite flood control and drainage works, divided into open-pit stope and the surrounding rocky flood interception project; stope the upper flood interception works and deep well drainage project. Among them, drainage system of mine drainage system is still the first time in chemical mine. Practice shows that this kind of flood control and drainage works is effective. Stope facades often maintain good working conditions. Groundwater and heavy rain rains have little effect on the slope of the stope and the management of the mine is convenient.
