Abstract: Because of the strict environmental protection requirement and the banning of highway transport of coal, Taiyuan Coal Preparation Plant as a central coal preparation plant is confronting challenges in raw coal supply, product quality and production organization related aspects. In order to cope with this situation, a perfect coal blending center is formed through further improvement of the existing raw coal, clean coal and by-products blending systems. Through the center, it is finally possible to have the raw coal, clean coal and by-products stored or out loaded either separately or in a blended manner, and to realize all-railway, transport of coal. The center proves to be a technologically matured reliable coal blending center of Taiyuan plant.
