METHOD OF MAKING COAL BRIQUETTES FROM OXIDISED COAL FOR MINED-LAND RECLAMATION

摘要

FIELD: fuel.;SUBSTANCE: invention describes a method of producing coal fuel briquettes from oxidised coal, including screenings of coal furnace burden from large fines, its mixing with the binder – aqueous solution of polyacrylamide with admixture of propylene glycol surfactant and “Biogum” humic preparation, briquetting, drying and packing the obtained briquettes.;EFFECT: technical result is obtaining coal briquettes with higher efficiency of recultivation and mined-land reclamation.;1 cl, 1 tbl, 7 ex
