This paper is dealing with the coal's reservation, production and transportation in mainland China during the last 40 years (1951-91).Up to 1991, total reservation of the coal fields throughout the country which investigated are: 889400×10^6 tons, total production of the coal in China at same year are: 108×10^6 tons.
Shansi province is still a leading coal production region, and the Southern China is still coal deficient area, Based on this situation, it appears two problems as follows:
1) Five east-bond railroads from Shansi have very heavy load throughout the year to the seaports of Northern China.
2) Five sea ports such as: Chinhuangdao, Tianjin New Port, Chingdao, Shijiugang, Lianyungang are also keep busy in order to transport the huge amount of coal from North China to South China and to go abroad.
Four maps and five tables are attached.
