简介:随着2022年冬奥会所有雪上运动项目将在崇礼县进行,届时将接待大量国内外游客,但是该县境内在冬奥会交通走廊及赛场周边共有7个露天开采矿山点,由此产生了大量的矿山地质环境问题,有损于城市形象,本次工作任务是消除奥运通道沿线矿山地质环境破坏对视觉景观的影响.本文选择其中最为典型的三道营铁矿有限公司铁矿为例,阐述其恢复治理的思路,以供探讨治理方案.思路为少投入,多见效,治理重点考虑水土保持措施和生态复绿效果.矿区中较大的废石堆、渣堆、露天采坑,主要采用削高填低、分阶整平、覆土绿化的治理措施,矿区地势较低、容易汇水的地段修建截排水沟,将地表汇水引入露天采坑储存,并可作为绿化用水.设计的矿山工程从施工可行性、施工工艺复杂性、环境治理效果、工程投资费用大小及效益产出等多方面,进行了分析对比.
