Exploration of Reclamation,Restoration and Reuse of Existing Mining Land for a Large Open-Pit Iron Mine Enterprise
Old mining enterprises generally have problems such as difficulties in obtaining new construction land indicators and low reclamation rates of existing mining land.Reclaiming and restoring existing mining land into ar-able land for reuse not only restores the ecological environment of the mining area,but also achieves retirement in-dicators,supporting the sustainable development of enterprises.This article takes a large open-pit iron mine enter-prise as an example to study and analyze the problems in the reclamation and restoration of the mining area.Through the implementation of governance measures such as"backfilling engineering,drainage and drainage engi-neering,stone backfilling and anti settlement engineering,and barrier layer construction engineering",the backfilling and rectification of the mining pit is completed.By directly using the topsoil removed from the planned damaged farmland for the reclamation of existing mining land,and to build irrigation and drainage facilities,roads,and other facilities and fertilize the soil.Reclamation of existing mining land into farmland can achieve good economic,social,and environmental benefits,providing reference for the subsequent restoration and reuse of similar mines.
