【摘要】：矿山固体废弃物资源化利用与处置一直是矿山与矿业领域关注和科学研究的重点。为满足矿山废弃地复垦与生态修复之需要,在山区自然混合土与植被特征调查研究的基础上,提出了矿山固体废弃物种植混合土及其配制方法。同时,通过了盆栽试验和地栽试验研究,结果显示:利用矿山固体废弃物与好土(细粒土),按本法能够很容易配制出适合植物生长的矿山固体废弃物混合土基质;利用这种矿山固体废弃物种植混合土进行矿山废弃地复垦与生态修复,不仅可以大量地消耗与处置矿山固体废弃物,而且能够快速地实现矿山生态恢复,较有效地防止泥石流、水土流失、环境污染等环境问题,其生态效益、社会效益和经济效益均较显著。
[Abstract]:The utilization and disposal of mine solid waste has always been the focus of scientific research in the field of mining and mining. In order to meet the needs of reclamation and ecological restoration of abandoned land in mines, the characteristics of natural mixed soil and vegetation in mountainous areas are investigated and studied. The mixed soil planted with mine solid waste and its preparation method are put forward. At the same time, the pot experiment and field planting experiment are carried out. The results show that the mixed soil matrix suitable for plant growth can be easily prepared by using mine solid waste and good soil (fine grained soil). The reclamation and ecological restoration of mine waste land by planting mixed soil with this kind of solid waste can not only consume and dispose mine solid waste in large quantities, but also realize the ecological restoration of mine quickly and prevent debris flow more effectively. The ecological, social and economic benefits of soil erosion and environmental pollution are significant.
