The Analysis And Prediction Of Chengde City's Mine Geological Environment

Cheng is a big mining industry city of He bei province, it makes a major contribution to national economic development with its abundant mineral resources. Meanwhile,due to years of large scale mining without environmental protection and treating work, mine condition and ecological context have been heavily damaged. Social development requires us to initiate mine environmental protecting project, not only for the strategy of sustainable development of'Population, Resources and Environment', but also to build a harmonious society and pleasant living environment .By field survey and investigation, and geological environment data collection of more than one thousand Chengde mines, a great deal of field data has been indoor sorted out and map plotting. Furthermore, study to evaluating indicator established10 rank second evaluate factors, and the utilize of hierarchical analysis-expert scoring method is applied to geological environment of every single mine of the city to make synthetical evaluation.With the grading standards, severe area, critical area and general area are marked off from points to entire surface to the mine geological environment of Chengde city. This paper makes trend analysis to mine geological environment issue of Chengde city from three aspects, and coming to a conclusion: the mining environment of this area will generally remain steady and be improved; environment issue of large scale mines will be improved;environment issue of small-sized village and private mine will still be outstanding.Through the analysis to mine geological environment problem of Chengde city, summarize some reasons and issues of mine environment disruption in this region, provides basic information and strategy support to rational exploitation of mineral resources, protects mine geological environment, controls mining circumstances, restore and re-construct the ecosystem of mine, as well as carries out management of mine environment surveillance.
