Research On Comprehensive Development Model Of Coal Mining Subsidence Area Based On Ecological Restoration Theory

Nanhu District,Hebei,Tangshan City province is located in the south of Tangshan City,was originally a wilderness wasteland.In the late Qing Dynasty,the governor of Zhili and the northern trade minister Li Hongzhang established the first modern coal mine in the history of china.After hundreds of years of coal mining and the influence of the 1976 Tangshan earthquake,the ground subsidence area,the underground artesian drainage water outburst ground,plus years of coal mining waste,urban garbage and construction waste piled up earthquake in 1976,the site has become a complex situation,serious pollution,the construction industry is almost impossible to wasteland,and the ground continues to sink,south of Tangshan urban development strategy lay hidden.The South Lake eco city southernmost,sagging periphery the most serious design as research object,through the design and research,to explore a feasible route for governance "mine pollution,land subsidence" type of Brownfield,for future ecological restoration in China a large number of production mining complex to provide the experience for reference.
