FIELD: mining.
SUBSTANCE: invention refers to mining and can be implemented at underground development of mineral deposits with stowing mined space. Stowage mixture contains, wt %: Portland cement or its milled clinker 1.4 - 13.68, milled zeolite rock 0.21-10.4, brine of 20÷105 g/l mineralisation, mainly of sodium chloride at temperature facilitating temperature of stowage mixture not below +15°C 14.9 - 26.96, fluidizing agent 0.01 - 0.3, filler - the rest. The invention is developed in dependant claims of the invention formula.
EFFECT: raised mobility and flowability of stowage mixtures, reduced shrinking at maintaining specified hardness, and reduced costs for nature conserving measures from negative effect of harmful salt saturated wastes of diamond extraction.
