The 21150 fully-mechanized face located at the east of junction of three drip in 21th mining area.The fore supporting between up-per and under roadway using hinged girder cooperate with single pillar to support,which influenced by stress of mining and serious deforma-tion.By field research and analyzing of reasons of deformation,putting forward using ZT2×4000/23/50 roadway support to replace hinged girder to support and strengthening the both ends with hydraulic support ,which have proved to be better,ensure the safe production of recovery face and guarantee the efficient production of recovery face at same time.
