Study On Environmental Influence Assessment And Mining Damage Influence Of Jian Zhuang Mining Area

Mine environment is currently a major challenge facing our country, environmental pollution arising from mining and geological disasters will cause a great impact on humanity's living environment. Vegetation and destruction of groundwater resources caused by mining subsidence damage aggravate soil erosion, which has caused long-term impact that is difficult to restore on balance of the ecological environment. The resulting secondary geological disasters are endangering people's lives and property. Therefore, the effective and scientific establishment mining area environmental evaluation system has important practical significance and application value to ecological and environmental protection on the mining and geological disasters prevention.This paper took Jian Zhuang mining area as an example, collected first-hand material about geological setting, mining methods, the mine exploitation present situation and so on, analyzed these data carefully, draw the conclusion that what are major environmental problems and the causes and characteristics. establish evaluation index system from three aspects that's the regional geological setting, mining and mine development status combined with the actual situation in mining areas. Used multi-level fuzzy fuzzy synthesize assessment method to carry on environmental impact assessment.With the further research of Jian Zhuang mining area Geological conditions,the maximum value of surface subsidence, the maximum value of horizontal movement, the maximum value of deformation and so on are expected using probability integration method in Jian Zhuang mining area. Verificated them with the measured value of Jiao Ping and Huang Ling mining area, because their geological and mining conditions is similar.Then determined reasonable parameters of surface subsidencein in in Jian Zhuang mining Area. Analyzed these data carefully,draw the conclusion that the mainly influencing factors are mining method ,burying depth,thickness,hardness of the overlying rock and so on. According to the predictions, given the Influence law of ground subsidence and the comprehensive control measures.
