The Government''s Official Website for the Office of Surface Mining Reclamation and Enforcement (OSMRE). OSMRE''s business practices are to reclaim abandoned mine lands (Title IV), regulate active coal mines (Title V), and apply sound science through technology transfer.
2 #0183;#32;Land reclamation, the process of improving lands to make them suitable for a more intensive use. Reclamation efforts may be concerned with the improvement of rainfalldeficient areas by irrigation, the removal of detrimental constituents from salty or alkali lands, the diking and draining of tidal marshes, the smoothing and revegetation of stripmine spoil areas, and similar activities.
For example, since the passage of the 1977 Surface Mining Control and Reclamation Act (SMCRA) in the, direct fees have been collected by government agencies from existing coal mining companies. Various states and Native American tribes have used over US billion of those funds to reclaim almost 240,000 acres of hazardous highpriority coalrelated problems.
Reclamation is often phased to e concurrent throughout the life of the mining project. Examples of successful reclamation projects include: A company reclaimed its mining pit to a strawberry field. A gravel extraction area at Mississippi Bar was returned to a riparian wildlife habitat. An aggregate mine on agricultural land operates in four phases.
Iron mining operations began on the Mesabi Range in 1884 where strip mining was the most common method used to gain access to the ore. The open pits mines and spoils banks formed from the removal of overburden to gain access to the ore are still present today. As the rich ore was depleted taconite mining operations began.

NRCS describes a threefold purpose for land reclamation: Prevent negative impacts to soil, water, and air resources in and near mined areas. Restore the quality of soils to their premining level. Maintain or improve landscape visual and functional quality.
The reclamation of disturbed land is conducted in one technological cycle with the process of manganese ore mining. The soil mass is taken off, piled up and heaped onto the land after the rock has been replaced. The effectiveness of different models of land reclamation and heavy metals migration through rocksoil plant system was researched.

A mining method including land reclamation and hydropower and water resources development including removing the ore from the ore body in a predetermined pattern so that the remaining ore body defines a grid network of cellular units, the ore removal being performed progressively such that adjacent cellular units are in various stages of development simultaneously and filling the minedout
Mine reclamation is the process of restoring land that has been mined to a natural or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started. Mine reclamation creates useful landscapes that meet a variety of goals ranging from the restoration of productive ecosystems to the
#0183;#32;Four categories of land for reclamation may generally be distinguished in coal mining according to the degree of biological reclamation difficulty (Greszta and Morawski, 1972): Ieasy reclamation, flat spoil heaps made predominantly of carboniferous shale, burnt or unburnt, and horizontal sedimentation ponds of coal silt with a high content of clay, loam, etc.;

Returning Mined Land to Productivity Through Reclamation
Mining reclamation in Brazil began only after public protest in 1977 at Belo Horizonte, the capital of Minas Gerais. The primary complaint was environmental degradation of the landmark Serra do Curral ridgeline above the city, caused by extraction of ore from a large openpit mine.
#0183;#32;In order to obtain satisfactory results in reclamation, special attention must be paid to the postmining use of the land and its potential functions (, pasture, hayland, recreational areas, wildlife habitat, wetlands, fishing ponds etc.), together with the implementation of environmental conservation and land reclamation programs to minimize the negative environmental effects (Cao 2007
Underground mining methods: Ore is natural rock that contains valuable minerals, Reduction of slopes by land infill and reclamation, growing plants and trees on mined areas will stabilise the soil and reduce erosion by binding the soil and protecting the ground.
