COAL INDUSTRIAL FLOW AND ITS RESOURCE AND ENVIRONMENT EFFECTS IN DIFFERENT PROVINCES
模拟山西、山东和辽宁三省的煤炭工业流过程，通过物质流分析将其分为资源投入和消费两个阶段，并利用资源自给率、煤炭消费结构和环境影响指标分析资源效率和环境效应。
After illustrating the route of coal use in China, coal industrial flow process is simulated in Shanxi, Shandong and Liaoning provinces respectively. Then the flow process is deducted into two stages, resources input and consumption by material flow analysis (MFA). Lastly, resource efficiency and environmental effects of coal industrial flow are analyzed by resource self-supply ratio, coal consumption structure, and environmental impact. Conclusions lie in: ①the self-supply ratio of coal and its products vary among different provinces. With coal flow deeply from resource to primary products, then to finished products, the self-supply ratio rise in different degree in various provinces.②The more coal and its products flow into middle industrial process such as washing, molding, coking, and gasification, the more the coal industrial structure is improving. Share of middle input in total coal consumption in Liaoning province is more than that of in Shanxi and Shandong province, and coal industrial structure in Liaoning is more perfect.③Weight of washed coal in total coal production is low, weight of reclaim of resource and its products is low, and output ratio of coal products from resource is low too in process of coal industrial flow in various provinces, which get rise to serious environmental impacts. The washed coal ratio and reclaimed coal ratio should be improved greatly.
