Research On Coal Railway Planing And Evaluation Under The Background Of Collection And Distribution System

China's unbalanced regional development, economics and geographical characteristics, resource distribution and the characteristics of the industrial layout and the status of the energy, resources and environment carrying capacity decide that the railway plays an important role in Chinese energy strategy. However, Chinese railway as the backbone of the integrated transport system and the main transportt, the problems of lacking of road network and disequilibrium of road network distribution are very prominent. In Western area, rapid expansion of coal demand lead to the transport capacity tension. Moreover,lacking of the large capacity channels has seriously hampered the development of China's economy.From the view of energy stratigic perspective, the planning, implementation, management and evaluation of Chinese coal railway infrastructure are explored in the context of the collection and distribution system. The coal railway system in state-owned group A and its major coal railway SH are taken as examples. The objective of this paper is to provide a theoretical suggestion and reference for Chinese energy strategy.According to supply chain management theory, the synergetic theory and comprehensive transport integration theory, the intension, characteristics, development motivation and elements of the coal railway collection and distribution system are discussed. The railway infrastructure are pointed to be the primary planning element in the coal railway collection and distribution system by the analysis of elements.According to the principle, accordance and objective, the factors affecting the coal rail infrastructure planning are analyzed. From the view of freight volume of coal railway and economics, the technical economy of the coal rail infrastructure planning is analyzed. The freight volume is analyzed by the forecasting of coal railway on the basis of the demand of coal railway and supply analysis. From the view of the cost, price and economies of scale of the coal rail way infrastructure, the economic feasibility of coal railway planning is analyzed. Moreover, From the aspects of road network planning and project planning, a comprehensive analysis of the coal railway infrastructure planning is proposed.On the basis of coal railway infrastructure planning, from the aspects of the implementation of the project planning and implementation of the project organization and management, the implementation of the coal railway infrastructure projects are discussed. The coal railway infrastructure evaluation framework and evaluation index system are built. Fuzzy comprehensive evaluation and gray system theory are used to conduct a comprehensive evaluation for the coal railway infrastructure.Finally, coal railway collection and distribution system planning of Group A and expansion and reconstruction project of its major coal railway line SH are taken as examples to verify the scientific nature and feasibility of the results of the theoretical studies in this paper.
