Description
Изобретение относитс к горной промышленности , в частности к укреплению отвальных пород обогатительных фабрик и карьеров . Известна композици дл повышени устойчивости отвальных пород, включающа вес. %: Мочевино-форм альдегидную смолу55 - 65 Хлористый аммоний0,1-2,0 ВодуОстальное Недостатком этой композиции вл етс токсичность феноло-формальдегидной смолы Наиболее близкой к предлагаемой по составу компонентов и достигаемому техническому эффекту вл етс композици , вклю чающа , вес. %: Карбамидную смолу39 - 45 Сульфат железа8-12 Фус43 - 53. Фус сол ержит следующие компоненты. вес. %: Т желые сланцевые 30 - 40 Минеральные частички 40 - 50 Остальное 2. Недостатком композиции вл етс ее многокомпонентность и высока величина газопроницаемости укрепленной породы. Целью изобретени вл етс снижение газопроницаемости и повыщение прочности пород отвального массива обогатительных фабрик. Это достигаетс те.м, что композици дл укреплени отвальных пород обогатительных фабрик содержит в качестве смолы смолу полукоксовани , а в качестве фуса - фус углетермического производства при следующем соотнощении компонентов, вес. %: Смола полукоксовани 85 - 90 фус10-15, где фус в свою очередь, содержит следующие компоненты, вес. %:The invention relates to the mining industry, in particular to the strengthening of dump rocks of beneficiation plants and quarries. A known composition for increasing the stability of dump rocks, including weight. %: Urea-aldehyde resin55 - 65 Ammonium chloride 0.1-2.0 Water Other The disadvantage of this composition is the toxicity of the phenol-formaldehyde resin. The composition, including weight, is closest to the proposed composition of the components and the technical effect. %: Carbamide resin39 - 45 Ferrous sulfate8-12 Fus43-53. Fus salt contains the following components. weight. %: Heavy shale 30 - 40 Mineral particles 40 - 50 Else 2. The disadvantage of the composition is its complexity and high gas permeability of the hardened rock. The aim of the invention is to reduce the gas permeability and increase the strength of the rocks of the dump array of the beneficiation plants. This is achieved by the fact that the composition for strengthening the dump rocks of the beneficiation plants contains resin of semi-coking as a resin, and coal-thermal production as a fusc at the following ratio of the components, wt. %: Resin semi-coking 85 - 90 fus 10-15, where the fus, in turn, contains the following components, wt. %:
Угольную смолу45 - 66Coal tar45 - 66
Частички полукокса33 - 50Semi-coke particles 33 - 50
ВодуОстальное.Water is the rest.
Смола полукоксовани и фус вл ютс Semi-coking resin and fus are
отходами углетермического производства. Закрепление пород предлагаемой композипией производитс путем инъекции смесиcoal production waste. Sealing the rocks with the proposed composite is done by injecting the mixture.
указанных компонентов, подогретой до + 60 -80°С.these components, heated to + 60 -80 ° C.
Примеры количественного соотношени компонентов предлагаемой композиции и результаты испытаний закрепленных пород на газопроницаемость и прочность при сжатии приведены в таблице.Examples of the quantitative ratio of the components of the proposed composition and the results of tests of fixed rocks for gas permeability and compressive strength are shown in the table.
