The global coal trade flows are determined by the allocation of coal resources in the international context, that is, the shift from coal rich areas to demand areas. From the geographical point of view, the regional international coal main flow by Germany and France led to Japan and South Korea and as the representative of the Asia Pacific region, including: EU coal imports mainly from North America and Eurasia; Japan and South Korea as the representative of the Asia Pacific region’s coal imports mainly from coal producing countries in the region (such as Indonesia, Australia). Judging from the proportion of international trade in global coal production, the trade level of coal is not high, accounting for less than 15%. Steam coal is the main type of international trade, accounting for about 70% of the total trade volume, and other coal species account for about 30%. From the form of trade, maritime transport is the main form of international trade, accounting for more than 90% of the total international trade.It is good for conveyor idler manufactures.

Coal is one of the most abundant, widely distributed and most economical energy resources in the world. According to the World Energy Commission data, as of 2013, the world’s proven recoverable coal reserves of about 8915 tons, mainly distributed in the Asia Pacific region, Europe and North America and Eurasia, three of total global reserves of recoverable reserves of 95%, the Asia Pacific region accounted for 32%, accounting for 28% of the area of North America, Europe and Eurasia accounted for 35%. In terms of country, the countries with the most abundant coal reserves are the United States, Russia, China, India, Australia and South Africa, accounting for about 75% of the coal storage in these 6 countries. Among them, the United States, Russia, China and India accounted for more than 10% of the world’s total storage.It is good for conveyor idler manufactures.

As the first industrial revolution of the main energy, although coal has completed its historic mission, but due to the characteristics of rich reserves and the use of economic, energy diversification in today, it still has strong vitality, especially in the developing nations led by China and India energy structure, coal is still the main energy source of demand. In 2013, the world’s total consumption of coal 38.3 tons of oil equivalent, accounting for 30.1% of the total energy consumption. Of these: coal provides 67.5% of China’s energy demand, providing India with 54.51% of the energy needs.It is good for conveyor idler manufactures.

The coal flow is mainly transferred from coal surplus to the supply of coal, the Asia Pacific region of the Atlantic in Europe and the Pacific is the main area of the world, including: the Atlantic coal imports in Europe’s coal imports mainly from neighboring America and Eurasia, the Pacific region’s coal imports are mainly from some coal Power Asia Pacific local (such as Indonesia, Australia), Africa exports to two regions were similar.
