Research on the Ecological Restoration of Coal Mining Subsidence Area in Shanxi Province

Coal mining in Shanxi is characterized by the most severe gob and subsidence in China, so its ecological restoration is strongly typical, exemplary and stimulating for the whole country. At present, most of domestic researches focus on land reclamation rather than the ecological restoration of subsidence area for coal mining. In terms of subsidence area, ecological restoration is no longer to simply restore the subsidence area to the available settlement land, but to establish a natural complex ecosystem which is totally or partially different from the function of original land and can be harmoniously integrated with the surrounding economy, society and economics, thus generating high economic, social and environmental benefits. This paper analyzes the specific causes of environmental problems in mining collapse regions, and learns effective and advanced experience to propose techniques and methods for ecological restoration as well as the countermeasures and suggestions.
