Abstract: The stability of hydraulic support in fully mechanized mining face of the coal seam with large dip angle has become
the focus and difficulty of research. This paper analyzed the relationship between the stress state of the hydraulic support and the
surrounding rock, as well as the factors affecting the stability of the support, studied the anti-slip and anti-fall of the hydraulic
support, and probed into the fault crossing technology.

 Key words: coal seam with large dip angle; support stability; fault crossing technology
