Collapse and the corresponding environmental geologic hazards because of mining activities have exerted serious impact on sustainable development of the mining area. The rapid control of the collapse and rehabilitation of the eco-environment are a very important prerequisite to the harmonious development of economy and environment. This paper analyzed the influencing factors and development mechanism for karst collapse of iron mining areas in Laiwu city based on the in situ investigations. Five indexes were selected to assess the hazard of the karst collapse, then the risk degree of the study area was assessed. Finally, the strategies based on the research results were put forward. The results of this research provide scientific basis for planning regional ecological restoration and sustainable development. And the assessment indexes and the method proposed in this paper serve as valuable reference for similar researches.
Key words： ecological rehabilitation; karst collapse; Laiwu city; risk
