Model calculation and analysis of geological environmental capacity in Qian'an Mining District Zhengsheng Li 1 a, Wensheng Liu 2,b , Haoran Guo3,c 1,3 Civil and Environmental Engineering School, University of Science and Technology Beijing,Beijing,100083,China 2 Nanshan Mining Co，Ma Steel Group, MaAnshan, 243000, China lizhengsheng0512@163.com Keywords: analytic hierarchy process, relative surplus rate, environmental bearing capacity, sustainable development Abstract.
Introduction Qian'an mining area is the raw material base of ShouGang Mining Company, has more than 50 years mining history , the main mining area in Qianxi ,One country of Qian'an City , Hebei Province , with the long-term mining , the main stope resources has gradually depleted with the ecological environment deterioration and the sharp contradictions between mine area and Qian'an City development , This paper puts forward the geological environment loading capacity evaluation model and the evaluation index system based on the theoretical of geological environment loading capacity , the optimal solution is determined by calculating for the rational use of mining resource with reasonable overall planning of the mine , which provides scientific basis for promoting to realize the sustainable development of Qian'an Mining area.
