摘要
某铁矿尾矿库库内支沟发育,右岸支沟距离初期坝较近,位于堆坝范围内,与主沟有山脊相隔.为安全排泄入库洪水、确保尾矿水澄清,结合场地地形地质条件,采取在主沟和右岸支沟分别设置排洪系统的方式.右岸支沟内初期采用排水斜槽-排水管,后期利用在山脊修建临时排水沟,主沟内采用排水井-排水管的方式.现尾矿库排洪出口水质清澈,运行正常.
Abstract
A development of branch gullies occurred inside an iron mine tailings pond,with the right bank branch gully being close to the initial dam,situated within the dam pile area,and separated from the main gully by a mountain ridge.In order to safely discharge floodwater from the pond and ensure the tailings water is clari-fied,a flood discharge system was put in place separately in the main gully and the right bank branch gully,in accordance with the site's topographic and geological conditions.Initially,a drainage chute-pipe system was used inside the right bank branch gully,and subsequently,a temporary drainage ditch was constructed along the ridge.Within the main gully,a drainage well-pipe system was used.Currently,the water quality at the tailings pond's flood discharge outlet is clear,and the system is operating normally.
