FIELD: mining.
SUBSTANCE: invention relates to mining and can be used in the development of steeply dipping ore deposits. The ore deposit is separated into tiers in height. The field is opened to the full depth or to the depth of known reserves and mined in ascending order. The lower and all overlying odd, regarding from below, tiers are mined with chambers with filling the chambers with dry rock fill, all the overlying even tiers - with the system with ore caving and host rocks. Even tier is mined after excavation of the chambers of underlying and overlying tiers and filling the least with the fill. The interchamber stopes within the tier between the chambers filled with dry rock and also mined with the system with caving.
EFFECT: invention enables to ensure the sustainability of the superincumbent bed during mining chambers and to reduce the area of damage of the earth surface.
