露天开采生态环境影响识别与修复技术的探讨——以崇阳露天石煤钒矿矿山开发环评为例

Discussion on Environment Impact Recognition and Restoration Technique of Opencast Working——taking EIA of opencast working coal vanadium mine in Chongyang as an example

矿山开采活动在获得最大的经济利益的同时,势必给原有的生态环境带来严重破坏和影响.结合矾矿露天采矿特点,讨论矿山开采各个环节对生态因子的影响及强度,筛选主要影响因子,分析露天矿山开采可能引起的地形地貌、土地占用、土壤侵蚀、破坏野生动植物生境、地表水水质、景观格局等方面对环境的影响,并提出相应的优化施工方案、闭坑露天矿山土地、植被复垦等生态环境保护对策,对科学开发崇阳钒矿具有一定参考意义.

exploitation activities always get profits as much as possible, but synchronously nature environment is destroyed seriously. The paper discussed impact and its intensity toward ecological factor brought by each step of mine exploitation, which involves physiognomy change, land occupation, soil erosion, habitat damage of wild vegetation and animals, quality of groundwater and landscape pattern. Moreover, it proposed corresponding optimum construction scheme and environment protection measures of land and vegetation restoration after the ending of mining with referenced meaning to rational exploitation.
