  • ateway in inclined coal seam is difficult to maintaine mainly due to its location in a remarkably anisotropic environment. The failure and deformation mechanism and pattern of gateway in inclined seam are analyzed by using discrete element method in combination with measurement of loose zone around gateway in field. It is proved that the upper side wall fails seriously and it is the key part to maintain the whole gateway. It is suggested that a comprehensive support pattern must be adopted including sidewall reinforcing.
