摘　　要：以平顶山四矿戊九采区下山专用回风下山底鼓控制为工程背景,介绍了深井煤层巷道底鼓特点及其控制原理.通过现场观测、理论分析、数值计算等手段,确定了该巷道的底鼓支护方案,监测表明,该支护方案较好地控制了底鼓,对深井巷道的底鼓控制具有一定的借鉴意义.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.
