Abstract：In order to promote the mine environmental restoration work,this paper put forward the definition of geo-environmental restoration model.It discussed the mine environmental restoration governance theory based on the complexity of mine environmental problems,which are the objectives,core technology and model construction.With the method of layer analysis,the dominant of restoration work is found;then the governance targets are divided and decoded into the objective of geological engineering,land-restoring and ecology-restoring;it summarizes four restoration technologies,including the misfortune-repairing technology,engineering repair technology,ecological restoration technology and bioremediation technology;finally,it puts forward a restoration governance model which is to-the-point,target-controlled and technology-determined.Take the coal mine subsidence basin as an example,this paper puts forward the objectives,requirements and techniques of restoration work in subsidence basins,and it constructs five mine geoenvironmental restoration models for subsidence basin problems.In two coal mine subsidence basins of Inner Mongolia and Hebei Province,the management were taken appropriately according to the local condition and the effects of restoration subsidence basin model were analyzed in the practical engineering.
