Abstract: An introduction is made in the paper to the course of the development of Taiyuan Coal Preparation Plant since its founding 6 decades ago. By closely keeping abreast of the situation of the growth of the national economy and the coal industry, the plant has undergone many times of large-scale technical renovation with market demand as guidance and through persistence of technological innovation and incessant introduction of new technology, new equipment and new processes. Through the efforts made, the capacity of the plant has gained 2 times of skyrocketing rises first from 2 Mt/a to 3 Mt/a and then from 3 Mt/a to 4 Mt/a. The plant will persist in the innovation-driven development preparation as the core. In the face of the new challenges, the idea of the development of 3 large bases and 4 industrial sectors and seeking development of the plant with unremitting efforts by shifting the business mode is proposed.
