尾矿固废型植生基材在矿山生态修复中的应用

Application of Vegetation Substrate by Tailings in Mine Ecological Restoration

矿山岩质边坡及废石场等废弃地因缺乏植物生长所必须的土壤条件,加之长期开采后矿山周边天然土壤贫瘠,可用于矿山生态修复的植生基材匮乏且昂贵。基于此,本文以矿山大量存在的尾矿固体废弃物取代天然土壤,对尾矿的性质进行改良,研制出可用于矿山生态修复的植物生长基质材料;同时根据矿山地质环境特点,综合采用植生槽、生态长袋、喷播绿化、种植孔穴等生态修复方法,在尾矿改良的植生基材上种植植物,进行矿山生态修复应用。本文的工程实践,可为相关矿山生态修复治理提供有意参考。

Due to the lack of soil conditions necessary for plant growth and the poor natural soil around the mine,the vegetation substrate for ecological restoration of the mine is scarce and expensive.This paper developed a vegetation substrate by tailings which can be used for mine ecological restoration;At the same time,according to the characteristics of mine geological environment,the ecological restoration methods such as planting trough,ecological long bag,hydraulic spraying seeding and planting hole were comprehensively adopted to plant on the vegetation substrate,the demonstration application of mine ecological restoration can provide a meaningful reference for related mine ecological restoration management.
