上层煤柱对下覆巷道掘进的承压影响与支护对策

摘要

In the advancing process of Fucun Coal Mine 3 下 401 wood lane, affected by mining-induced stress, the roadway roof baseboard has significant advancement, and roadway support is difficult. This paper analyzes the reasons of compression deformation of roadway, and puts forward some countermeasures for the support of successful implementation in the construction site, which ensured the safety construction.%付煤公司3下401材巷在掘进过程中受采动应力影响，巷道顶底板移近量显著，巷道支护困难。文章分析了巷道受压变形的原因，提出的支护对策在施工现场得到了成功实施，保证了安全施工。
