Abstract
Изобретение относитс к горной промышленности и предназначено дл закладки выработанного пространства твердеющими смес ми (ТС). Цель - повышение прочности закладочного массива и снижение стоимости закладочного материала за счет утилизации отходов промышленности. Состав ТС содержит следующие компоненты, мас.%: отходы обогащени калийных руд 20,0-80,5 и хвосты флотации серных руд 19,5-80,0. Тонкие фракции указанных компонентов ТС перемешиваютс в заданном соотношении. Вода при необходимости добавл етс в ТС с учетом влажности компонентов дл получени достаточной пластичности ТС. Прочность образцов в 28-дневном возрасте составл ет 31-43 кг/см2. 2 табл.The invention relates to the mining industry and is intended for laying the mined-out space with hardening mixtures (TS). The goal is to increase the strength of the backfill array and reduce the cost of the backfill material due to recycling of industrial waste. The TC composition contains the following components, wt%: potash ore dressing wastes 20.0-80.5 and flotation tailings of sulfur ores 19.5-80.0. The fine fractions of these TC components are mixed in a predetermined ratio. Water, if necessary, is added to the TC, taking into account the moisture content of the components to obtain sufficient ductility of the TC. The strength of samples at 28 days of age is 31-43 kg / cm 2 . 2 tab.
Description
Изобретение относитс к горной промышленности и может быть использовано при подземной разработке месторождений полезных ископаемых с закладкой выработанного пространства .The invention relates to the mining industry and can be used in the underground mining of mineral deposits with the laying of the goaf.
Цель изобретени - повышение прочности закладочного массива и снижение стоимости закладочного материала за счет утилизации отходов промышленности.The purpose of the invention is to increase the strength of the backfill array and reduce the cost of the backfill material due to recycling of industrial waste.
Использование преимущественно тонких фракций хвостов флотаюта серных руд характеризуетс следую-- щим гранулометрическим составом, представленным в табл.1.The use of predominantly fine fractions of the tailings of the flotilla of sulfur ores is characterized by the following particle size distribution presented in Table 1.
При обогащении серных руд на серных предпри ти х сбросные хвосты флотации в виде водной суспензии откачиваютс в открытые хвостохранилища , где по мере протекани раздел ют-, с (путем естественного оседани ) на две группы, отличающиес в основном крупностью частиц. Крупные Ф15акции обезвоживаютс и могут непосредственно отправл тьс на закладку . Тонкие фракции смешиваютс с отходами обогащени калийных руд в заданном соотношении по твердой фазе.During the enrichment of sulfur ores in sulfur enterprises, the flotation tailings in the form of an aqueous suspension are pumped out into open tailings, where they are divided as they flow, with (by natural sedimentation) into two groups that differ mainly in particle size. Large F15 units are dehydrated and can be directly sent to the bookmark. The fine fractions are mixed with the waste of potash ores in a predetermined ratio of the solid phase.
Вода при необходимости с учетом влажности исходных компонентов добавл етс в количестве, требуемом дл получени хорошей растекаемости смеси. Результаты испытаний образцов приведены в табл.2.Water, if necessary, taking into account the moisture content of the starting components, is added in the quantity required to obtain a good flowability of the mixture. The test results of the samples are given in table 2.
