英文摘要：

The engineering background is the west main return airway dip of Ji San wining district of No. 4 mine in Pingding Shah mining district in this paper. The phenomenon of underground pressure and principle of surrounding rock control of deep shaft coal roadway are introduced. The supporting pattern of this roadway is determined by field observe, theory analysis, numerical simulation. Engineering monitoring indicates that the surrounding rock of the roadway is controlled by the new supporting pattern. It is of important significance for deep roadway to be supported.
