回采巷道超前支护金属铰接顶梁布置结构分析

Analysis of Metal Articulated Beam Arragement Construction in Forepoling of Entry

结合高应力、大变形回采巷道条件,对金属铰接单梁和十字铰接梁组合使用的两种布置结构,从架设工艺和使用效果等方面进行了分析比较,为回采巷道超前支护中更好地推广使用金属铰接顶梁提供了借鉴。

Combined on high stress and big deformation entry,metal articulated single beam and cross-articulated beam were used with combination,it was analyzed from designed craft and result,and a good experience was raised for spreading metal articulated beam in forepoling of entry.
