Open mining pit ecological restoration structure and application
The invention provides an ecological restoration structure for an open mining pit and application, and particularly relates to the technical field of solid waste treatment. The ecological restoration structure for the open mining pit comprises a foundation stratum, an impermeable layer, a backfilling area, a blocking layer and a vegetation restoration layer which are sequentially stacked from bottom to top. Wherein the backfilling area is filled with metal mine flotation tailings. According to the ecological restoration structure for the open mining pit, the impermeable layer and the blocking layer are adopted to seal the backfill area, rainwater is prevented from entering the backfill area, and flotation tailings are effectively blocked. The backfill area is filled with the flotation tailings as a matrix material, ecological restoration of the abandoned mining pit is completed, and meanwhile resource utilization is conducted on the solid waste tailings.
本发明提供了一种露天采坑生态修复结构和应用，具体涉及固废处理技术领域。该露天采坑生态修复结构包括由下至上依次层叠的基础地层、防渗层、回填区、阻隔层和植被恢复层；其中，所述回填区内填充有金属矿山浮选尾矿。本发明提供的一种露天采坑生态修复结构，采用防渗层和阻隔层对回填区进行了封闭，阻隔雨水进入回填区，对浮选尾矿进行了有效阻隔。采用浮选尾矿作为基质材料填充回填区，不仅完成了废弃采坑的生态修复，同时对尾矿这种固体废物进行了资源化利用。
