Abstract: Economical and intensive land use has always been one of the research topics for mine construction.Based on the design and construction of a metallurgical mine project,the sharing of social resources,combined and intensive construction,advanced and efficient technology of filling and mining,scientific and reasonable overall layout plan and vertical design,and land acquisition in phases,were studied so as to reasonably control the indexes of land use for construction,optimize the arrangement of land use and enhance the utilization ratio of mineral resources and the contribution of land resources to the economic and social development.In this way,the mine has noticeably saved the construction land of 327.67 hm2.Thus,it is very essential to study on economical and intensive land use technology in mine construction at the design stage.The wastes in mine production can be fully recycled to eliminate the discharge of pollutants and protect the ecological environment to the maximum.Land reclamation plays an important role in economical and intensive land use,so the mine design should cover the planning of land reclamation after construction,so as to facilitate the economical and intensive land use of mine construction,promote sustainable social development and realize sustainable utilization of land resources.

Key words: Mine construction, Economical and intensive, Land use technology, Land reclamation
