摘　　要：超前液压支架是维护巷道顶板支护的重要装备,根据柳巷煤矿回风巷道地质赋存条件,采用数值模拟方法分析超前巷道应力分布规律得出巷道超前支护距离及支护强度,通过现场实测得到巷道表面位移变化趋势,为柳巷煤矿回风巷道超前液压支架选型及设计提供依据。Advanced hydraulic support is an important equipment for maintain roadway roof supporting, based on geological situation of ventilation roadway of Liuxiang coal mine, advanced roadway stress distribution law was studied by numerical simulation method, and then roadway advanced supporting distance and supporting strength were put forward, the change law of roadway surface conver-gence was obtained by filed testing,it references for ventilation roadway advanced hydraulic supports selection and design of Liuxiang coal mine.
