The Study Ofassessment On Mining Geo-environment Influence And Preventive Measure In Muscovite Ore Mine In Danba County

The massive exploitation of mineral resources is one of the important factors thatmake resources and environmental crises. With the development of mineral resources, theimportance of ecological and environmental protection have become more important.Andthe mineral location cannot be selected，many mining companies will be there for a longtime，they will bring much intensive destruction to the arable land and the protected areas，it will trigger a series of social，economic and ecological problems. How to coordinate themineral development and the protection of the natural environment, maintain a sustainabledevelopment between the natural ecosystems and the human activities? That’s an importantissue to be resolved.And it has important meaning that dividing mine geological environment properly，make country and district carry the case of protecting and treating geological environmentinto execution directively.This paper will take Danba as the research area, through to the Danba minefieldsurvey，rom geological environment problems，with geological environment background，select the reasonable evaluation standard， reference at present the mature regionalgeological environment evaluation model and method， set up a system of the minegeological environment impact assessment system for the mine geological environment torestore the government work and the rational development and utilization of mineralresources planning to provide the scientific basis.The paper draws following conclusion are as follows:1,The ecological environment of Danba County is very fragile. The leadingdevelopment industry of the city is muscovite mining and it highly dependents on landresources and mineral resources，biological resources predatory mining，large area becomeecologically vulnerable areas. 2,The evaluation method is a comprehensive evaluation measures basing onqualitative evaluation. The impact extent of geological environment in all regions will bereceived through comparing the geological environment impact scale index with theenvironmental status.3,The Danba County mine geological environment affect the partition was gottenbasing on combining the evaluation results with the actual environmental situation inDanba County. The result was that the number of seriously influence dare as was3，and thenumber of more influence dare as was1.4,According to Danba mine geological environment influence partition conclusion，evaluation area can be divided into priority control area，and general priority control area.5,The reasonable decorate prevention and control engineering could be designedbasing on the kinds of environmental problems and impact extent.
