摘要： 霍州煤电集团丰峪煤业地质条件复杂，为解决薄煤层开采带来的衔接紧张等问题，通过对11#煤层顶底板特性
的研究，利用高水材料对工作面回风巷侧采空区进行充填，已达到沿空留巷的目的。通过对现场数值模拟监测分析，确
定在不同充填宽度情况下，巷道在垂直方向应力应变及巷道顶底板位移量的变化趋势，得出在充填宽度为1.2 m时，配合
沿空留巷加强支护，最终能有效控制围岩变形。

Abstract: Geological condition of Fengyu Coal Industry of Huozhou Coal Electricity Group is complex, and high water material
were filled in the back side of airway goaf in order to solve cohesion tension and other problems brought by thin seam mining
based on study on the characteristics of roof and floor of 11# coal seam. With field numerical simulation monitoring and analysis,
the stress-strain in vertical direction and change tendency of roadway roof and floor displacement were determined, and it was
obtained that strengthening support of gob-side entry retaining with filling width of 1.2 m can finally effectively control the deformation
of surrounding rock. Key words: siltstone roof; thin coal seam; high water material; gob-side entry retaining
