Abstract: In order to study the roof movement features of fully-mechanized top coal mining in soft large inclined angle seams, the overlaying strata displacement, r oof weighting step and mining pressure appearance were researched by using analogy simulation tests and the field monitoring. The results showed that overlaying stra ta sinked asymmetry and maximum subsidence decreased with increasing height in the process of mining face. The greatest strength and biggest weakness of mining p ressure appearance were upper and lower part, taking on faster in the middle than in the ends. The maximum abutment pressure was in 17 ~ 25 m ahead the working fa ce, the support strength should be strengthened within 40 m ahead the working face. The test results and field observation were in substantial agreement, which could provide the guidance references to the hydraulic powered support selection.
