Ecological restoration method for resourced iron ore wasteland

Abstract

The present invention relates to an ecological restoration method for resourced iron ore wasteland. The method comprises three parts of tailings removal and resource utilization, landform reshaping and land use re-planning. Specifically, the method comprises comprehensively reusing existing waste tailings resources, processing the tailings resources into environmentally friendly materials, reducing various pollution and hazards, and achieving a purpose of resource recycling; and land after a recycling and harmless treatment is subjected to the landform reshaping, including three parts of subsidence area filling, landform landscape design and topographic water and soil conservation, local topography and landform are reshaped, local landscape new land value is granted, finally re-plan of theland is conducted, suitable tree species for planting are selected, and ecological environment of mine is restored. The method can recycle tailings resources, can also greatly reduce investment in aprocess of ecological restoration of the wasteland, can also conduct land resource reuse according to different types of lands and achieves a purpose of regional coordinated development according to local conditions.

Description

technical field [0001] The invention relates to the field of soil ecological restoration, to the technical field of tailings treatment, and in particular to a method for ecological restoration of resource-based iron ore waste land. Background technique [0002] Northeast China is rich in mineral resources and has a long history of mining and mining, which has made great contributions to the country. However, problems such as ecological damage, environmental pollution, and secondary geological disasters brought about by the development of mineral resources have seriously affected the sustainable development of the region and become an important factor restricting the revitalization of Northeast China. The open-air wasteland encroached on a large area of ​​forest land and farmland, causing damage to the land use function. At the same time, the iron tailings piled up in the open air contained a large amount of heavy metal substances, which also caused huge pollution and harm to...
