新阳矿新102综放工作面材料巷超前支护段由于受多重支承压力和新102工作面采动影响，变形严重、支护困难，在详细分析巷道超前支护段变形破坏机制的基础上，提出了“锚网＋W钢带＋锚索＋U型钢棚”的联合支护方案，并在超前工作面30 m范围内采用ZT2×3200/18/35型超前支护液压支架加强支护，在超前工作面30～100 m范围内采用“单体支柱＋π型钢梁，1梁3柱”的加强支护方式。现场观测表明，材料巷超前支护段顶板下沉量由原先平均27mm/d减少到8mm/d，保障了工作面安全生产，加快了工作面推进速度，提高了经济效益。

In Xinyang Colliery , serious deformation and difficult supporting occurred in advanced supporting section of rail roadway of new 102 full-mechanized caving mining face influenced by multi-time abutment pressures and new 102 face mining.On the basis of an-alyzing deformation and damage mechanism of the roadway , a combined supporting of “anchored mesh+W steel strip+anchored cable+U-style steel” scheme was put forward.Within 30m of advanced supporting , ZT2×3200/18/35 advanced powered support was applied to reinforcing supporting.At the range of advanced 30-100m, reinforcement supporting of “single prop+π-style steel beam, 1 beam+3 props” was applied.On-the-spot observation showed that roof subsidence reduced from 27mm/d to 8mm/d.This technology increased mining speed and improved economic profit in safety.
