FIELD: soil or rock drilling; mining.
SUBSTANCE: invention relates to mining industry and can be used in development of deposits of various minerals with laying of mined-out space, as well as for filling of various recesses and open pits. Composition of stowing mixture for filling mine workings includes waste metallurgical slag and activator. At that, waste slag contains nickel production slag, activating additive is activating additive sludge obtained by neutralization of ferrosilicon calcium slag with spent hydrolytic sulphuric acid, besides, mixture additionally contains tailings of mine workings separation, at the following ratio, wt. %: nickel production slag - 22…23; tailings for mine workings separation - 66; activating additive slurry 11…12.
EFFECT: technical result is to increase strength of stowing mixture, increased volume of recycled technogenic wastes and improved environmental friendliness.
