Abstract: According to the occurrence characteristics of 12124 fully mechanized coal face with large inclined angle in Panbei Coal Mine, aiming at prone pseudo inclined mining problem of large inclined angle, we design the parameters of prone pseudo inclined mining with large inclined angle, determine the machine tail docking 4 stents and 4 blocks scraper conveyer chute in the prone pseudo inclined mining early, which guarantees and effectively control that glide quantity of hydraulic support in each cutting is 304 mm. And through the implementation of key technologies including the connection of antiskid jack among conveyors to reduce conveyor glide, reasonable control of the support mining height and stent distance, and increasing the anti-friction layer thickness of coal winning machine sliding boots to ensure the normal working face advance, and realize 12124 prone pseudo inclined fully mechanized working face in large inclined angle, and achieve good economic and technical effect.
