Abstract: Abstract:It is all kown that the support of inclined coal seam gateway with expansile soft rock has always been very difficult,it is very hard to control the deformation of surrounding rock under traditional support forms. Based on the engineering of 1202 mining face at the tenth coal mine of Hebi,this article analyses the destruction reasons of inclined coal seam gateway with expansile soft rock and puts forward bolt-mesh-cable-belt coupling support technology,this technology has been verified in the engineering. It also analyzes its applicability in the similar roadway.

Key words: Key words:inclined coal seam gateway, asymmetric, coupling support
