Problem Global Mining Bring

Mining environmental issues have regionally and particularity these two characteristics,which for a long time have not gained much attention, with the rapid economic development and social progress, people's living standards gradually increase, the ecological and environmental problems are received more and more attention,  the  appeared mine edging environment problem began to receive attention once again, such as the environmental pollution and ecological destruction that mining, magnetic separator ,ball mill and smelting activities caused has become a global environmental and geological problems, which is also an important area of environmental geochemistry research.
Mining also cause the problem of forest vegetation destruction. Forests are the main body of terrestrial ecosystems, which have an extremely important role in keeping the global ecological balance, regulation of climate, soil and water, reduce floods and other natural disasters, a variety of forest products have a wide range of economic uses. However, from a global point of view, the destruction of forests is still a serious problem faced by many developing countries, a series of environmental consequences caused by this received people's attention gradually.
 
Take the loess Plateau in China's development and production of the first modern large opencast coal mine - An ATB Opencast Coal Mine as example,based on the mine land reclamation and ecological reconstruction, they build the mine ecological system and its control theoretical framework, the proposed mining area land use control technology system geographic information system platform of the mine land cover change, and to establish the mine primary land use dynamic integrated model, and use the integrated model to analyze the driving force of the mining area of ??human activity on the land, environment , the effectiveness of the results show that the basis for large-scale open-pit land use change characteristics of mine land use dynamic change process is divided into two phases, namely ecological destruction process of land-use change land digging, land pressure accounting, land tenure and ecological reconstruction process of land use change landscape remodeling, soil reconstruction, revegetation of land use covering the evolution of characteristics of the performance of rapid mobility for space, and land elements of variability stages of sustainable land, land type complexity Antaibao Open The total land area of ??mine land use change analysis revealed that in 20 years, the mine ecosystem maintain the form of the original landform ,In addition to the expropriation of unoccupied land, other land use covering all change mining damage 2003.07hmwoodland is the most obvious changes.
