Description

Изобретение относитс  к креплению подземных горных выработок, а именно к крепи сопр жений выработок скреперовани . Известна крепь сопр жений выработо скреперс вани , включающа  набрызг - бетон в сочетании с железобетонными анкерами и металлический трос .-ЧНедостатком такой крепи  вл етс  незначительна  сопротивл емость действию динамических и сейсмических нагрузок , в результате чего вокруг анкеров возникает отслоение пород и они обнажаютс  на значительную длину тер   несущую способность. Известна также друга  крепь сопр жений выработок скреперовани , включающа  рамы податливой крепи, соединенные между собой лобовинами и зат ж ками 2 . Недостаток такой крепи заключаетс в том, что над сопр жением образуютс  вывалы, при этом отслоившиес  кус породы скатываютс  в дугки. Цель изобретени  -,предотвращение вывала над сопр жением. Это достигаетс  тем, что вдоль каж дой лобовины установлены с интервало сгтержни, свободные концы которых вве дены в восстающие шпуры. На фиг.1 изобра){сена крепь сопр жений выработок скреперовани ,поперечное сечение; на фигГ2 - разрез А-А на фиг .1. Крепь сопр жений выработки скреперовани  состоит из податливых рам 1, лобовин 2, зат жек 3 и стержней 4, которые установлены налобовинэ 2 с интервсшом, при этом свободные концы стержней 4 введены в восстающие шпуры 5. Крепь сопр жени  возвод т следующим образом. Устанавливают, податливые рамы 1 и соедин ют их между собой лобовинами 2/ затем укладывают зат жки 3. После этого бур т восстающие шпуры 5 и ввод т в них стержни 4 так, что.бы концы их не доходили до дна шпуров на 20 см, затем нижние концы стержней скрепл ют с лобовинами 2. Крепь сопр жений, работает следующим образом. При взрывах порода кровли над сопр жением разрушаетс  и отделившиес  куски породы стрем тс  скатитьс  в дугки. Стержни 4 удерживают породу над сопр жением, не допуска  ее падени  в дугки.The invention relates to the fastening of underground mine workings, namely to the support mating of excavations of scraping. The known support for the joints of vani scrapers, including spraying - concrete in combination with reinforced concrete anchors and a metal cable. The lack of such support is the slight resistance to dynamic and seismic loads, as a result of which around the anchors there is detachment of rocks and they are exposed to a considerable length ter bearing capacity. Another well-known lining of the scrapings of the workings of the scraping is also known, which includes the frames of the pliable lining, interconnected by lobling and tightening 2. The disadvantage of such lining is that dumps are formed over the mating, while the exfoliated couscous rocks roll into arcs. The purpose of the invention is to prevent a fallout over mating. This is achieved by the fact that, along each lobovina, shafts are installed at intervals, the free ends of which are inserted into the rebel holes. In Fig. 1, an image {hay lining of the mating openings of scraping, cross section; on FIG. 2 - section A-A in FIG. 1. The framing of the framing mating siding consists of flexible frames 1, lobovins 2, tack 3 and rods 4, which are installed with nalobovine 2 with an interval, while the free ends of the rods 4 are inserted into the re-erecting holes 5. The mating is erected as follows. Install the pliable frames 1 and connect them to each other with lobers 2 / then put the puffs 3. After this, the rebel holes 5 are drilled and the rods 4 are inserted into them so that their ends do not reach the bottom of the drill holes by 20 cm, then the lower ends of the rods are fastened with the ends 2. The attachment support works as follows. During explosions, the rock of the roof over the mating is destroyed and the separated pieces of rock tend to roll into arcs. The rods 4 hold the rock above the mating, not allowing it to fall into arcs.
