Abstract: The design of supporting scheme is one of the key technologies to ensure the safe and efficient production of underground coal mines. The 150913 return air roadway in the 14 mining area of Tucheng Mine intends to adopt the combined support of anchor mesh cable + W steel belt + T steel belt. In order to achieve the overall goal of economic and rational support effect, the theoretical calculation and numerical simulation method are used to calculate and verify the roadway support parameters. The results show that 13 bolts are constructed in each row of 150913 return airway, including 11 bolts on the top of three-center arch and 1 bolt on each side of two sides. The row spacing between bolts is 900 mm× 900 mm, and 5 anchor cables are constructed in each row. The row spacing between anchor cables is 1800 mm, which can ensure the production safety of mining area and improve the efficiency of roadway excavation.
