Abstract:As the high-speed of economy,the activity of exploiting coal is becoming frequently. The larger mining space,the stronger mining intensity. With the increasing frequency of mining,the scope of subsided area also becomes huge. As a result,coal mining subsidence area brings much damage to the environment of mine. This paper based on the current situation of Huainan coal mining subsidence area discusses the feasibility of constructing model-late floodplain,in the view of city planning which combining with the factors of geography and hydrology as well as the space evolution. We use ArcGIS develop the evaluating system of Zhangji, as well as the calculating tool. And we consider some related data,demonstrating the new pattern of floodplain on the field research of Zhangji coal mining subsidence area in Huainan.
Keywords:coal mining subsidence area;novel floodplains;ArcGIS;the pattern of exploiting and utilizing
