The basic situation of the coal industry production in Shanxi province was studied in this paper, and the transportation of coal in Shanxi province which was divided into the highway freight and the railway freight was studied. Then, the analysis method of synthetic degree of grey incidence was improved by the three-point estimate method in the program evaluation and review technique method in order to analyze the coordination of coal production and coal transportation more precise. The result showed that the length of railways and the length of highways are the key factors to promote the coal industry production in Shanxi province. And the mean of the improved synthetic degree of grey incidence of the railway transportation of coal and coal industry production in Shanxi province is larger than that of the highway transportation. More attention should be paid to the construction of the railways in order to promote the coal industry production in Shanxi province. Keywords-coal industry production; coal transportation; coordination; synthetic degree of grey incidence; three-point estimate method
