FIELD: mining.
SUBSTANCE: present invention pertains to mining industry and can be used in exploiting mineral deposits with goaf stowing. The technical result can be achieved by that, to the composition of the stowage mixture, containing steel-making slag and activator sludge, burnt rocks from mining dumps are added, and the activator used is sludge, obtained from liming spent electrolytes of lead-acid traction batteries.
EFFECT: higher strength, with use of readily accessible wastes from the local industrial raw material base in the stowage mixture.
