Abstract: Based on computing and analyzing the mine pressure observation data of 2401 working face,the strata behavior regularity and the surface displacement regularity of mining roadway are researched, besides that,the the adaptability of powered supports are analyzed.The research results show that,selecting of powered supports are reasonable and adaptability of the powered supports are good,which can provide a reference to the similar conditions for controlling of the mine pressure and selection of the hydraulic supports.

Key words: Fully mechanized caving faces, Strata behavior regularity, Surface displacement of roadway, Selection of the hydraulic supports
