Abstract
Use of traditional technologies by development of deposits of the minerals having hard layers of a roof and ground, becomes complicated difficulties of management of mountain pressure. In these conditions have gained distribution the technologies providing оставление of sights for maintenance of the basic roof. To leave a pillar sights conducts to significant losses of a mineral. Use of a bookmark instead of sights gives a gain of stocks of a mineral, raises efficiency and safety of mountain works. In work data about effective areas of descent and transport dry stowing materials in mountain developments are cited.
