Изобретение относитс i; горпой промышленности и может быть использовано при креплении горных вырг|бо1Ч к.The invention relates to i; mountain industry and can be used for mounting mountain vyrg-bo1Ch.
Известны бесстоечн1,е закладные верхн кн , особенностью К(;тс;рых вл етс то, что они вставл ютс в предварительно пробуренные в боках выработки у ее кровли ниши 1 .Known bestoyachn1, e mortgaged upper kn, a feature K (; ts; loo is that they are inserted into the niche 1 previously drilled in the sides of the workings at its roof.
Известен также способ установки бесстоечной крепи, включаЮи1ий разделку боковых HHUJ, бурение в нишах шнурпв с последующим закреплением в них анкеров дл поддержани верхн ка, установкой и расклиниванием их.There is also known a method of installing a bottomless lining, including cutting the side HHUJs, drilling in the niches of the cord, followed by securing the anchors in them to support the top, installing and wedging them.
Этот способ осуществл ют конструкцией бесстоечной крени, состо иий из ве)хн ка с опорными площадками на концах, клиньев и анкеров, устанавливаемых нишах 2.This method is carried out by the construction of a decay-free roll, consisting of a veil with support sites at the ends, wedges, and anchors installed in niches 2.
Недостатком этих способов вл етс невысока надежность креплени выработки.The disadvantage of these methods is the low reliability of fastening production.
Целью изобретени .с ноп1 инение надежности креплени .The aim of the invention is to ensure reliable fastening.
Это достигаетс тем, что ннши в боках выработки у ее кровли разделывают с наклонны .ми стенками, а расклининапие верхп ка производ т между его о 1Орными площадками и наклонными стенка.мн HHHI, опорные площадки выполнещ на1.:|()нными, аThis is achieved by cutting its upper walls at its roof with inclined walls, and wedging the tops of the tops between its 1Or platforms and inclined mHHHI walls, the supporting platforms are 1:: () (), and
клинь расно;1ожепы .между ними и стенками НИН1 и установлены на стержн х )в с возможностью перемен 1е1Ц1Я вдо.1ь их осей.wedge rasno; first burns between them and the walls of NIN1 and mounted on rods) with the possibility of changes 1e1TS1I with their axes.
На чертеже изображена выработка с устацовленной в ней беестоечной крепью.The drawing shows the development with bestestoyanno in it bestestoechnoy lining.
Предлагаема крепь состоит из верхн ка 1, к которому с помощью хомута 2 креп т опорную площадку 3, опирающуюс на закрепленный на ст(ржне анкерной к|5епн 4 с помощью планки 5 н гайки 6 клип 7.The proposed support consists of a top 1, to which a support platform 3 is fastened with a clamp 2, supported by a support (mounted on an anchor anchor | 5пн 4 with a clip of a 5 n nut 6 clip 7.
Крепление выработки производитс с.педуюн1им образом.Fastening production made s.peduyanu way.
По мере пррведепи выработки у ее кровли разделывают боковые нищи с нак.чонными стенками, на которые устанавливают ерхн к 1 с ирикрепленными к его концам с помощью хомутов 2 опорпыми площадками 3. Клип 7 устанавливают на стержне анкерной крени 4, дл чего в боковых нишах бур т щпуры, в которые вставл ютс анкеры . Подпор верхн ка осуп1еетв,л ют нуте.м перемещени с помощью гайки 6 раснорно1Ч) клина между опорной площадкой 3 н нак.чонной стенкой нинц-1.As the production is done at its roof, the side bends are cut with nak.chonnymi walls, on which they install the top to 1 with 2 supporting pillars 3 fixed to its ends with clamps 3. The clip 7 is mounted on the anchor roll bar 4, for what in the side niches of the drill t holes in which anchors are inserted. The support of the upper part of the shaft is pushed forward by means of the nut 6 of the razorno-1H) wedge between the supporting platform 3 and the ninz-1 dark wall.
