Abstract: Abstract：Thick coal seam through a small coal mine on the formation, the roof structure of upper formation is very complex, and the mining of the lower coal seam may have a significant adverse impact, which brings great influence for support of the mining roadway below. Aiming at the complexity of the roof structure of 8101 integrated mine roadway, roadway characteristics are classified, and proposes a dynamic roadway timbering principle. The optimization and selection of support parameters are carried out by means of theoretical analysis and numerical simulation, finally determine the roadway using scheme with cable anchor support and shed support supplemented by the "supporting dynamic partition". Field practice shows that the deformation of surrounding rock in a reasonable range, meet the requirements of safe production, roadway research results can provide the reference for the similar condition.
