摘要
介绍了在大埋深、高应力集中区域采用锚网索梁与u型棚子联合支护巷道帮顶,通过双重支护使巷道收敛变形量控制在一定的范围之内,减少了翻修复修工程量,满足回采期间巷道的通风、行人需要。
The paper introduces that the cable anchor beam is combined with u shed to support the roadway roof in large embedded depth, high stress concentration area. The double support makes convergence deformation of roadway controlled within a certain range, reducing the overhaul repair quantity, and meeting the needs of the roadway ventilation and pedestrians during the mining.
