Research On The Application Of Air Quality Model In Planning Assessment And Optimization Of Coal-mining Areas

As the development of China’s economics, the features of the air pollution has presented as regional and synthesized pollution. Thus China has been building up a new mode of air pollution controlling which merges the emission, total emission and the quality controlling of air. Strategic environmental assessment is an effective method to solve the regional air pollution problems. As China built up the master of SEA technical guidance in 2014, the theoretical, technical and institutional study has developed a lot, but the technical approaches’ study is still lack.This study is aimed at studying and discussing the proper air quality model for the SEA of the coal-mining area. Then applies the air quality model to the study area of Yangquan Coal-mining Area and predict the effect of the conventional pollutions. At last, an optimized scheme is designed to optimize the site of pollution sources, which will reduce the pollution and make pollution concentration meet the National Standers.First of all, the study concludes and contracts the theory, the structure and the calculating blocks of conventional air quality models. By synthesized the characteristics of coal-mining areas, the study select CALPUFF as the most optimized model of simulating the air quality in coal-mining areas.Next, this study makes investigations and statistics of the main pollution sources in Yangquan Coal-mining Area. Then the air pollution concentration is stimulated and predicted by applying CALPUFF model. After that, this study calculates the statistics parameters of the simulated values and the measured values of monthly averaged concentration in 9 monitoring stations to verify the effectiveness of CALPUFF model. Then the study analyzes the spatial and temporal distribution of the pollution in Yangquan Coal-mining Areas.At last, the study selects the principal pollution source and makes a plan to optimize the station of the pollution source combining with the theory of planning. This optimization can make the air quality meet the National Secondary Standard both in the recent planning and in the long-term planning.The study of this paper offers certain of basis and technical reference in applying the air quality models to SEA of coal-mining areas which is definitely complicated in terrain and difficult in pollution sources’survey. At the same time, the study offers some guidance and really makes sense of the optimization of pollution sources by SEA.
