The main modes of coal transportation include railway transportation, road transportation, water transportation, etc.
Railway transportation
Railway transportation methods are divided into standard tracks and narrow tracks. Narrow gauge railway transportation is generally mainly used in small heat source factories within or near coal mines.
Standard railway transportation is an important method of transportation outside the factory. It has the characteristics of large transportation volume, long distance, fast speed, and is not limited by climatic conditions.
The railway coal transportation volume in China has always accounted for over 60% of the coal transportation volume, and the coal transportation volume accounts for about 40% of the total railway cargo transportation volume.
Road transport
Highway coal transportation is an important supplement to railway and waterway coal transportation, with characteristics such as flexibility, reduced occupancy, adaptability to terrain conditions, and cost.
Low cost and diverse types of transportation equipment. The main coal production bases and the hinterland of coal transfer ports have always had partial or short distance direct transportation by road or centralized transportation by road.
Although large-scale long-distance coal transportation is not an advantage of road transportation, in recent years, with economic development and a significant increase in coal demand, railway transportation has continued to be tense, and road coal transportation has developed rapidly. Road transportation is mainly influenced by the size of the coal price difference. The larger the coal price difference, the greater the profit space for people transporting coal, and the faster the development of road coal transportation.
Water transportation
Water transportation is an important mode of transportation and a commonly used natural transportation route for urban and rural construction in inland water areas of China. Water transportation utilizes natural rivers, rivers, lakes, and sea navigation methods to form roads, railways, and convenient transportation networks, suitable for medium to long distance transportation. The transportation volume is large, the freight cost is low, the maintenance cost is low, and the infrastructure investment is low. However, the waterway transportation time is long, and some navigation routes may be affected by seasonal water level changes. When the factory is close to the waterway terminal and the raw coal transported by waterway can meet the requirements, waterway transportation can be considered.

Other transportation
In addition to the three transportation methods of railway, highway, and waterway, the raw coal for pit power stations and boiler rooms can also be transported by aerial ropeways or long-distance belt conveyors.
The advantages of aerial cableway transportation are strong adaptability to natural terrain, large transportation capacity in river valleys, rivers, simple loading and unloading facilities, and small footprint. The disadvantage is that the investment and operating costs are relatively high.
The advantages of long-distance belt conveyor transportation are long transportation distance, continuous transportation, large transportation volume, long service life, and low equipment cost. By using aerial ropeways and long-distance belt conveyors for transportation, raw coal can be directly unloaded to the warehouse. Reduce secondary landing losses of raw coal, improve environmental pollution, and reduce equipment assembly.
