Abstract: According to the problems of asymmetric deformation and difficult supporting of large section roadway roof in deep
mine, this paper analyzed asymmetric deformation characteristics and the reasons of large section chamber roadway combined with
the actual geological conditions of coal mine, and put forward the asymmetric support scheme of roadway, which obtained a good
control effect of surrounding rock in the engineering practice to provide the reference for similar roadway roof control.

Key words: large section roadway; roof; asymmetric damage; reason; coupling control
