Understanding abandoned mine land (AML) changes during land reclamation is crucial for reusing damaged land resources and formulating sound ecological restoration policies. This study combines the linear programming (LP) model and the CLUE-S model to simulate land-use dynamics in the Mentougou District (Beijing, China) from 2007 to 2020 under three reclamation scenarios, that is, the planning s...

Concern for the potential global change consequences of increasing atmospheric CO has prompted interest in the 2 development of mechanisms to reduce or stabilize atmospheric CO . During the next several decades, a program 2 focused on terrestrial sequestration processes could make a significant contribution to abating CO increases. The 2 reclamation of degraded lands, such as mine-spoil sites, ...

Early studies of mine reclamation emphasized trees for revegetating minesoils. Scientists of the USDA Forest Service transplanted four tree species in 1946 into leveled or unleveled overburden near Georgetown, OH, and into unleveled overburden near Dundee, OH. Black locust (Robinia pseudoacacia L.) had good initial survival on both sites but died in later years due to locust borers (Megacyllene...

In the last decade several mining areas and corresponding dumps are subject to reclamation process in Bulgaria. We focused our research on one of the most important in the copper production for 20 year period for our country – Medet deposit. This mining complex consists of an open cast mine, the overburden dumps and a processing plant. After ceasing its exploitation in 1994 a rehabilitation pro...

Surface mining for coal has contributed to widespread deforestation and soil loss in regions around the world, particularly Appalachia, USA. Mined land reforestation is of interest this other where forests are dominant pre-mining use. This study evaluated mine development on surface-mined sites reforested according Forestry Reclamation Approach, representing a chronosequence time ranging from 0...

This paper gives step-by-step instructions for assessing aquatic selenium hazards associated with mining. The procedure was developed to provide the U.S. Forest Service with a proactive capability for determining the risk of selenium pollution when it reviews mine permit applications in accordance with the National Environmental Policy Act (NEPA). The procedural framework is constructed in a de...

The geochemical characterization of the mine deposits and soils in metal mining areas is essential order to develop an effective reclamation strategy. determination total potentially toxic element (PTE) content, together with application chemical extraction procedures, can give insight into behavior contaminants after different solutions, as well identify where urgent action needed. This work p...

The concentrations of metals in the buried marine sediment and groundwater were differently affected by land reclamation. Nine metals (V, Cr, Mn, Co, Ni, Cu, Zn, Cd and Pb) in sediment and coastal groundwater from reclamation areas in Shenzhen were examined. The gradually decreased concentrations (V, Cr, Mn, Ni, Cu, Zn) in sediment and relatively higher concentrations (V, Cr, Mn, Co, Ni, Cu and...

Land reclamation has been a common practice to produce valuable land in coastal areas. The impact of land reclamation on coastal environment and marine ecology is well recognized and widely studied. It has not been recognized yet that reclamation may change the regional ground water regime, which may in turn modify the coastal environment, flooding pattern, and stability of slopes and foundatio...

In 1980, an experimental opencast lignite mine was developed to compare redistributed A horizon with three minesoil mixtures as growth media for woody plants. The three minesoil mixtures contained different amounts and types of overburden materials, and normal reclamation practices were followed. Loblolly pine (Pinus taeda L.), sawtooth oak (Quercus acutissima Carruthers), yaupon (Ilex vomitori...
