The Geo-Environment Of Mining Area And The Influence Of Town Constructionin Yangcheng Of Shanxi Province

The development and utilization of coal resources make great contribution for the economic development and also produce many environmental problems. Such as mining environmental pollution, mining geological disasters, mining ecological destruction and so on. These problems have been seriously restricted the development of social economy.This paper takes imperial associated coal of Yangcheng Country as the research object. By field survey and investigation, and material collection of regional geological conditions and coal resources development situation, analyses the geological environment of imperial associated coal. The study found that the geological environemnt problems of imperial associated coal include mining geological disasters such as ground depression and fissure caused by coal mining, occupation and destruction of land resources, pollution and destruction of water environment. Through to analyse the causes and characteristics of mining geological disasters, concluded that the formation of-mining geological disasters related to mining geological environment conditions, coal seam characteristics, coal seam thickness, mining depth and the strength of human activities, and so on.The method of mine geological environment assessment references mature model of regional geological environment assessment, combines the actual situation of imperial associated coal, from mining geological disasters, the resources damage and regional geology environment background three aspects select the appraisal factor, establishes appraisal system, chooses Analytic Hierarchy Process(AHP) to determine the weight of every appraisal factor and evalutes the mining geological environment. Conclusion:so far, the mining geological environment quality of imperial associated coal is better. In the later process of coal mining, mining activities is feasible as long as plan mining area reasonablly and manage the environmental problems in time.Based on mine geological environment assessment, this paper mainly discusses the impact of town buildings and urban public facilities by coal mining. Through to calculate the maximum value of surface deformation, concluded that the surface buildings will be seriously damaged after repeat mining of No.3coal seam. In the end, this paper puts forward control measures of mining geological environment problems, and protection measures of surface buildings.
