矿产资源开发区生态环境问题及其防治

The Ecological Environment & Geological Environment Problems in Mining Zone and its Protection

矿产资源开发给周围地区的生态环境带来巨大影响。矿山剥离废矿石和脉石堆、矿山选矿废石、尾矿、冶炼熔渣、矿山酸性排水、土壤重金属元素、河流及其沉积物中的重金属、大气污染等都极大地影响了矿山地质环境、周边及其下游生态系统。地质环境保护是环境保护中的重要组成部分,是环境保护工作的基础。有效、合理开发和利用矿产资源,减轻对地质环境的破坏程度,减少地质灾害的发生将直接关系到整个生态环境保护。

The ecological environments around mining zone are affected to great degree by the exploitation of mineral resources. Geological environments and downriver water system are seriously polluted as well by the factors such as piles of disused ores and gangues, waste residues from dressing, tailings, melt slag, acid drainage, heavy-metal elements in soil, heavy metals in river and their sediments and polluted atmosphere. Geological environmental protection is basis of ecological environment protection, and it relies on efficiently and reasonably exploiting mineral resources, and reducing the damages in geological environment conduced to decreasing geological disasters.
