Аннотация

An analysis of the constraints that apply the technology and the complexities of the mining and geological conditions of the Quang Ninh coal basin. The possibility and expediency of using the  foreign experience of working out of the medium thick inclined coal seams in the mines of Vietnam.  The scheme of preparation and working out of the excavation area is given in view of the technological features in difficult mining and geological conditions, using the room and pillar system and determination of the ra-tional length of the block along the strike.
