The coal resources in China are mainly distributed in northwest parts, especially in Shanxi Province, north part of Shanxi Province and west part of Inner Mongolia, while the areas which consume coals most are the north and central south parts, thus the pattern of transporting coals in north to south and transporting coals in west to east comes into being. Coal transportation has been being the key point of railway transportation for a long time. Strengthening the railway construction for coal transportation to ensure safe and steady coal supply is significant to the safety of national energy strategy.
