摘　　要：为了解决厚煤层开采中沿空掘巷围岩变形难以控制的问题,文章研究了不同顶煤厚度和巷道埋深对巷道围岩变形的影响,并提出了有效的支护方案。研究结果表明,顶煤厚度和巷道埋深对巷道围岩变形有显著影响,通过优化支护方案可以显著降低变形量,所选支护方案有效控制了巷道围岩变形,提高了巷道稳定性。In order to solve the problem that it is diffi cult to control the deformation of surrounding rock in gobside entry driving in thick coal seam mining,this paper studies the influence of different top coal thickness and roadway buried depth on the deformation of roadway surrounding rock,and puts forward an effective support scheme.The results show that the thickness of top coal and the buried depth of roadway have a significant influence on the deformation of roadway surrounding rock and the deformation can be signifi cantly reduced by optimizing the support scheme.The selected support scheme effectively controls the deformation of roadway surrounding rock and improves the stability of roadway.
