Abstract：Coal-mining subsidence may not only cause a serious damage to local ecological and geological environment, but also constrain the sustainable development of local economy and society. Yongcheng, a typical city of coal resources in Henan Province, has a single economic structure and serious ecological problems. The year of 2012 had seen a subsidence of coal mining area and 271 villages, involving 37 000households and more than 120 000 people, resulting in a tense human-land relation. The study proposes that the protection of ecology and the improvement of local people's life should be given top priority when management policies and systems are made. Moreover, environment-friendly skills and green coal-mining technology should be emphasized. Last but not least, the restoration of the geological mining environment and the reclamation of lands in mining areas should be carried forward.
