中文摘要: 采矿废弃物酸化是全世界范围内一个较为普遍的现象,对矿区及其区域环境具有长期危害,是全球采矿业面临的最严重的环境问题之一。以德兴铜矿水龙山废石堆为例,从工程技术的选择、稳定性安全技术措施、污染防治技术措施、植物种类选择与配置等方面详细介绍了硫化矿废石堆场酸性污染控制与生态修复的工程技术方案,通过不同植物配置模式和不同覆盖隔离的对比实验,筛选出了最佳植被模式,同时采用覆盖措施后,有效的控制水的入渗,淋溶液的pH显著升高,Cu含量显著降低,实现了将“源头控制”的与生态修复有机结合,从源头上有效控制了污染的产生。从而为硫化物废物堆场环境污染的源头控制与生态修复工程产业化提供技术支撑。
Abstract:Acidification of mining wastes is a popular phenomenon worldwide. It has long-term harm to the mining area and regional environment, and thus it"s one of the most serious environmental problems for the mining industry worldwide. Taking Shuilongshan waste rock dump of Dexing Copper Mine for example, the paper provides a detailed introduction to the acidic pollution control and ecological restoration engineering plan from the perspective of selection of engineering technology, stability and safety technology and measures, pollution prevention and control technology and measures, selection and allocation of plant species, etc, and selects the optimal vegetation mode by contrast experiments on the allocation modes of different plants and coverage isolations. And after coverage measures are adopted, water penetration is efficiently controlled, pH of leachate is increased eminently, Cu content is lowered remarkably, the combination of "source control" and ecological restoration is realized, and pollution is controlled at the source effectively. Thus this provides technical supports to control of environmental pollution at sulphite wastes dump and industrialization of ecological restoration projects.
