FIELD: mining, particularly mineral mining with goaf stowing. ^ SUBSTANCE: stowing mix includes cement, namely 300 cement, milled granular slag and water. The filler is technological iodine modified sulfur and ash from thermoelectric power station. The iodine modified sulfur and the ash are fused with each other and milled in ball mill. Above components are taken in the following amounts (% by weight): 300 cement - 4.2-7.0, sulfur - 19.4-29.26, ash - 10.1-15.24, granular slag - 26.7-39.6, iodine - 0.0038-0.0058, remainder is water. ^ EFFECT: increased stowing mixture strength, homogeneity, manufacturability and pouring convenience without strength reduction, possibility to substitute expensive natural component for artificial ones obtained from industrial ore mining and smelting waste, improved environmental situation and decreased area of industrial waste storage. ^ 1 tbl |
