ANALYSIS OF MAIN COIMPOSITION FACTORS OF CYCLIC-FLOW TRANSPORT SYSTEM FOR A SURFACE COAL MINE

Based on the analysing principle of main composition factors in statistics, used the set upmodels, the production conditions of sub-systems of cyclic-flow coal transport system in Fushun's WestSurface Coal Mine are comparatively analysed. Through the analysis,the arranging order of production subsystems according to good and bad conditions is gotten. In accordance with the arranging order and practicalsituation of the cyclic-flow system,the future analysis is made and suggestions are proposed. Therefore, atheoritical basis for surface mine optimization design and production management is provided.
