Abstract Pillar width and support parameters were two important factors in coal mine production. In order to analyze and determine rational pillar width and relevant support parameter of Shanlang Mine, theoretical analysis method was used to find main factors of affecting coal pillar preserve width and relevant factors that affected choice of support parameters. As a result, the practice showed that coal pillar width of Shanlang Mine was determined as 15~25 m. Meanwhile, diameter, length, separation distance and array pitch of anchor bolt support were determined as well.
