Abstract: The BeijingTianjinHebei region is an important economic growth pole in China.Mine mining provides material support for regional construction,but it also left serious mine geological and ecological environmental problems such as crag,earth′s surface sinking,exposed bedrock,decreased vegetation coverage,and dust.In order to promote the coordinated development of the BeijingTianjinHebei region and construct a "capital water conservation function zone and ecological environment support zone",the geological environment management and ecological restoration situation of abandoned mines in the BeijingTianjinHebei region is urgent.Took the eastern mining area of Sanhe in Langfang City,Hebei Province as an example,analyzed the geological and ecological environment problems in the abandoned mining area,combined the regional natural conditions and ecological environment,proposed detailed targets for mine restoration,and proposed a complete set of technical solutions.The study provides technical support for the mine restoration in the BeijingTianjinHebei region,and provides a reference for regional mine restoration and environment improvement.
