Description
Известны химические реагенты самоуплотн ющихс забоек, состо щие из раствора сол ной и лимонной кислот и стекл нной капсулы с бикарбонатом натри . При взаимодействии этих компонентов образуетс углекисv4bm газ, «оторый расщир ет ампулу внутри шлура. Педостатком таких забоек вл етс мала надежность и опасность в обращении. Кроме того, снар жение и заполнение ампулы осуществл етс в специальных помещени х на поверхности.Chemical reagents of self-sealing bays are known, consisting of a solution of hydrochloric and citric acids and a glass capsule with sodium bicarbonate. When these components interact, carbon dioxide v4bm gas is formed, which opens the ampoule inside the slurry. The downfall of such tamping is low reliability and danger of handling. In addition, the ampoule is filled and filled in special rooms on the surface.
Отличием предлагаемого хи.мического реагента вл етс то, что он состоит из смеси карбоната натри , кристаллической щавелевой кислоты и экстракта солодкового корн в соотношении 1:1:1.The distinction of the proposed chemical reagent is that it consists of a mixture of sodium carbonate, crystalline oxalic acid and licorice extract in a 1: 1: 1 ratio.
Это позвол ет повысить безопасность и эффективность взрывных работ.This makes it possible to increase the safety and efficiency of blasting.
Па чертеже показана предлагаема забойка .Pa drawing shows the proposed stemming.
Она состоит из пластмассовой ампулы 1 с лепестковым затвором 2. Внутрь ампулы помещен химреагент 3, покрытый влагоизодирующим слоем. Затвор а мпулы выполнен изIt consists of a plastic ampoule 1 with a petal gate 2. A chemical reagent 3 is placed inside the ampoule, covered with a moisture-proof layer. Shutter and mpula made of
того же материала и такой же толщины, что и ампула, и представл ет собой лепесток, закрепленный одним концам на утолщенной части горловины.the same material and the same thickness as the ampoule, and is a petal attached to one end at the thickened part of the neck.
Ампула заполн етс шахтной водой в забое перед зар жением шпуров. После ее заполнени поверхности лепестка и утолщенной горловины смачиваютс и за счет сил сцеплени плотно прижимаютс друг к другу. Перед тем как поместить ампулу в шпур, химреагент раздавливаетс , и вследствие химической реакции образуетс пенно-газова среда, расшир юща ампулу и перекрывающа сечение шпура.The ampoule is filled with mine water in the bottomhole before charging the holes. After it is filled, the surface of the petal and the thickened neck are moistened and, due to the adhesion forces, are pressed tightly against each other. Before placing the ampoule in the hole, the chemical is crushed, and a foam-gas medium is formed due to a chemical reaction, expanding the ampoule and blocking the hole section.
Предмет изобретени Subject invention
Химический реагент дл самоуплотн ющейс забойки, отличающийс тем, что, с целью повышени безопасности и эффективности взрывных работ, он состоит из смеси карбоната натри , кристаллической щавелевой кислоты и экстракта солодкового корн в отношении 1:1:1.A chemical reagent for self-sealing stemming, characterized in that it consists of a mixture of sodium carbonate, crystalline oxalic acid and licorice extract in a ratio of 1: 1: 1 to increase the safety and efficiency of blasting.
