| In recent year,with the development of people's social and economic activity,and people's excessive exploitation of natural resources,the problem of our country mining geo-enviroment is more and more serious.At present,there are so many researches about single problem of mining geo-enviroment,but the sdudy on whole mining geo-enviromental problems,which has kinds of problems of geo-enviroment that think about many influencing factors,is just at the very beginning.As a result, evaluating and dividing mining geo-enviroment can provide scientific basis for the government carry the case of protection and governance of mining geo-enviromental problems,so the research is of great theory value and actual meaning.As investigation on the 4th mine of Jiangcang in Qinghai Province has got a lot of first hand data for the paper such as mining geo-environment background,exploit method and mining develop current situation.By the fact that analysis to mining geo-environment background and problems of ining develop current situation studies, summarizing that the main mining geo-environment problem of the 4th mine of Jiangcang are resources of soil and water, environment of soil and water, geologic hazard.And to ascertain that the area to study is 9.9375km2.The studied area was divided into 84 evaluated units,and the analysis of the assessment system and model were established with 13 first level assessment factors. Applying two methods of grey relationship and multi-fuzzy synthesize evaluation to assessment of mining geo-enviroment influence in the 4th mine of Jiangcang.The studied area was divided into 3 parts which according to the evaluation and actual circumstance:the influence of mining geo-enviroment is serious, less serious and normal.The result has testified that assessment factors,evaluation system and method chosen are reliable and effective,matcing the actual circumstance.According to the evaluation,the measure to protect and govern mining geo-environment were set forth.
