The coal gangue raw powder was activated by thermal activation technology, and the changes of mineral composition of thermal activated coal gangue were analyzed. The experimental results show that the coal gangue in Liupanshui mining area has the characteristics of high silicon and high-speed railway. After the coal gangue was activated at 800鈩，
