In order to discuss the support failure mechanism of the mining gateway support in the deep mine with a depth of 1 000 m and to solve the support difficulty of the mine gateway ,a monitoring and analysis was conducted on the deformation and failure law of the railway gateway in No.1304 coal mining face of the deep mine with a depth of 1 000 m of Zhaolou Mine in Juye Mining Area.Based on the circumstances ,finite difference software FLAC3D was applied to optimize the support plan and pa-rameters. Finally with the site monitoring and measuring ,verification was conducted on the optimized plan effect. The site monitoring and measuring showed that the site support effect of the optimized plan was excellent and the convergence between the roof and floor was reduced over 30% than the pre-vious support plan. The mine gateway support was passed the mining operation and the estimated tar-get of the gateway support was reached.
