Study On Environment Geology Problems For Iron Mine Enterprise In Tangshan

Mineral resources play an important basic role in social development, because they are necessary material conditions to human beings. In recent years, with the increasing of mineral resources exploitation strength increasing,the damages from mine geology environment are getting worse and worse. So mine geology environment and concomitant geohazard have become big geoenvironment issues which limit mine development in China. The mine environment geology problems have aroused people's attentions.According to the theory of iron ore develop, environment geology problems which caused by iron ore exploited in Tangshan has been summed up from mine geological disaster, mine pollutants and mine environmental damage. Meanwhile analyzed its characteristics, causes, against and performance. Environment geology problems target appraisal model has been established according to the characteristic of fuzzy mathematical theory. Used Delphi to make sure the target membership degree and used AHP to make sure the target weight. The results of target weight shows that mud-rock is the largest disservice and mine shake is the least disservice to iron ore develop in mine geological disaster. Waste water pollutants is the gravest and yawp pollutants is the feebleness in mine pollutants. The destruction of water resource is the gravest in mine environmental damage. Used fuzzy mathematical theory to appraise this model and realized that mine environmental damage have the largest influence on iron ore development and mine geological disaster is the second, mine pollutants is the feebleness. By caculation, the final decision-making value is 80.205 and the degree is"big".Based on the appraisal results, to put forward the prevention and cure measures about the main environment geology problems. Wasted iron mine were integrated utilized to prevent the occurred of dilapidation. From purification and callback to cure waste water pollution.
