Abstract: The sealed coring device for an underground coalbed comprises a rib drill pipe assembly, a tail bearing pack, a motor cylinder assembly and a sampling cylinder assembly. The rib drill pipe assembly consists of a rib drill pipe, a tail drill pipe joint and a head drill pipe joint. The tail bearing pack is mounted in the tail drill pipe joint and configured for protecting an internal structure from relatively rotating during drilling of the rib drill pipe, so that the stability of the sampling cylinder is ensured. The motor cylinder assembly is mounted in the rib drill pipe and configured for providing power for action of a center shaft in the sampling cylinder assembly.
