(54) СПОСОБ УСТАНОВКИ АНКЕРНОЙ КРЕПИ(54) METHOD OF INSTALLATION OF ANCHOR STRAP
1one
Изобретение относитс к креплению горных выработок, а именно к способам установки анкерной крепи.The invention relates to the fastening of mine workings, and in particular to methods of installation of anchor lining.
Известен способ установки анкерной крепи , включающий заполнение предварительно пробуренного в кровле шпура в жущим раствором и введение в него армирующего металлического стержн , установку опорной плиты и закрепление хвостовика стержн 1.There is a method of installing anchor lining, including filling the hole previously drilled in the roof with a trenching solution and introducing into it a reinforcing metal rod, installing a base plate and securing the shank of the rod 1.
Недостаток такого способа заключаетс в отсутствии мер против коррозии выступающего в выработку хвостовика армирующего элемента, опорной плиты и элементов креплени , что сокращает срок службы крепи, снижает длительную устойчивость выработок .The disadvantage of this method lies in the absence of measures against corrosion of the reinforcing element protruding into the production of the shank, the support plate and fastening elements, which shortens the life of the support and reduces the long-term stability of the workings.
Наиболее близким к предлагаемому вл етс другой способ установки анкерной крепи, включающий бурение ступенчатого щпура с устьем увеличенного сечени , введение в щпур анкера и размещение его хвостовика с опорной плиткой внутри уширенного усть щпура 2.Closest to the present invention is another method of installing anchor bolts, including drilling a stepped shpur with an enlarged cross-section mouth, introducing an anchor into the shpur and placing its shank with a support tile inside the broadened shpura 2 mouth.
Однако при таком способе также не обеспечиваетс предохранение концевой части анкера от коррозии.However, with this method, the end portion of the anchor is also not protected from corrosion.
Цель изобретени - предохранение концевой части анкеров от коррозии.The purpose of the invention is to protect the end portion of the anchors from corrosion.
Поставленна цель достигаетс тем, что устье шпура заполн ют изолирующим в жущим составом.This goal is achieved by filling the hole of the hole with an insulating composition.
5 Способ осуществл ют следующим образом .5 The method is carried out as follows.
В кровле горной выработки бур т ступенчатый щпур 1. С помощью известных устройств , например расщирител , установлен ,Q ного на буровом щнеке, расшир ют устье шпура 2 до размеров, на 8-12 мм превышающих поперечные размеры опорной плиты и на 8-12 мм - хвостовик штанги по глубине. При этом длину щпура увеличивают на величину, равную глубине расшир емой зоны. Затем в жущим веществом 3 заполн ют шпур 1, включа расширенную устьевую зону 2, устанавливают армирующий элемент 4, опорную плиту 5, крепление детали 6 с заделкой последних изолирую2Q щим в жущим составом 7, например, бетоИО1Й или раствором. При креплении горных выработок щахт по добыче пильных известн ков обеспечивает достаточную коррозионную стойкость состав, включающийStep bit 1 is drilled in the roof of the mine workings. With the help of known devices, for example, an expander, a foot is installed on the drill tongue, the hole 2 of the hole 2 is expanded to a size that exceeds the transverse dimensions of the baseplate by 8-12 mm and - the shank of the rod in depth. In this case, the length of the core is increased by an amount equal to the depth of the expandable zone. Then, a hole 1, including an expanded wellhead zone 2, is installed in the tandem substance 3, the reinforcing element 4, the support plate 5, the fastening of the part 6 with the sealing of the latter by insulating 2 with a tamping compound 7, for example, a concrete OR or mortar. When fastening the mine workings of the sawmill mining, it provides a sufficient corrosion resistance to the composition, including
цемент и мелкозернистый карбонатный песок в соотношении 1:0,5.cement and fine-grained carbonate sand in a ratio of 1: 0.5.
