| Abstract: | According to the large cross section open-off cut,the surrounding rock serious deformation failure and other features of the fully mechanized longwall top coal caving mining face in the soft thick seam,the paper firstly analyzed the stability of the roof in the mining face based on as the continued mass beam theory.Then the paper calculated the failure of the two side coal mass and seam instability.Finally,the paper had a numerical simulation and an optimized support parameters for the different bolt,steel mesh and anchor support alternative.A safety and economic support alternative was selected.The site industrial trial showed that the support alternative could meet the project engineering requirements with good economic and social benefits. |
| Keywords: | as continued mass bolt steel mesh and anchor limit analysis method numerical calculation |
