FIELD: mining.
SUBSTANCE: in charging steam bag with spacer gate, which includes suspension part made from organic material, for example from plastic mass and polyfractional charging part with predominance of crushed stone with fraction size of 10-20 mm in the first portions, according to the invention, the suspension part is made in the form of a reservoir with thickened bottom, which has biconical shape.
EFFECT: simplifying the design of combined stem bag due to rejection of housing of the suspension part.
