Description

Изобретение относитс  к горнодэбываю- шей промышленности. Известе} способ креплени  ходовых печей на крутых ппастах дерев нными анкерами с метаппической сеткой. В устойчивых угл х такой вид креплени  обеспечивае необходи гую надежность выработки и безопасность работ ij. Однако этот способ креплени  печей не предусматривает крепление сопр жений горных выработок. Известен также способ креплени  горных выработок анкерной крепью с использованием металлических подхватов . Недостатком такого способа креплени  горных выработок анкерной крепью с применением метаппических, в том числе и гибких подхватов  вл етс  то, что участок сопр жени  выработок поддерживаетс .креп недостаточно надежно, особенно в выработк пройденных по крутым и наклонным пластам угл . Целью изобретени   вл етс  повышение надежности поддержани  сопр жени  выра боток, Зто достигаетс  тем, что установку гибих подхватов в местах сопр жени  горных ыработок производ т путем огибани подхваами углов сопр жени  выработок. На фиг. 1 показано крепление сопр жени  ходовой печи со сбойкой; на фиг. 2 - крепление сопр жени  восстающей выработки с промежуточным штреком. Ходова  печь 1, закрепленна  дерев нными анкерами 2 и обт нута  по периметру сечени  металлической сеткой 3, сопр гаетс  с горизонтальной выработкой - сбойкой 4,закрепленной дерев нной рамной крепью 5,На сопр жени х указанных выработок устанавливаютс  гибкие металлические подхваты 6, прикрепл емые к горно. массиву анкерами 7, огиба  углы сопр гаемых выработок. Горные породы под етаппическими подхватами 6 всплошную перет гиваютс  металлической сеткой 3 или дерев нными зат жками 8, В сбойке подхват 6 проходит }.ад верхн ком первой, усипенной анкерами 9 рамы 5 и закрепл етс  анкерами 10.The invention relates to the mining industry. Lime} method of fastening the running furnaces on steep paspas with wooden anchors with a meta grid. In stable coal, this type of attachment ensures the required reliability of production and safety of work ij. However, this method of fastening furnaces does not provide for securing the interfaces of mine workings. There is also known a method of securing mine workings with anchor using metal pickups. The disadvantage of this method of fastening anchors with anchor lining with the use of metappic, including flexible grabs, is that the interface of the excavations is supported reliably, not sufficiently reliably, especially in the excavation of coal covered by steep and inclined seams. The aim of the invention is to increase the reliability of maintaining the mining ratio. This is achieved by installing bend pickups at the mining sites by bending around the corners of the mining openings. FIG. Figure 1 shows the attachment of an undercarriage mating with a coupling; in fig. 2 — fastening of the mating of rising production with intermediate drift. A running furnace 1, fixed with wooden anchors 2 and covered with a metal net 3 along the perimeter of the cross section, is mated with horizontal workings - sovoy 4, fixed with wood frame fixture 5. On the openings of these openings, flexible metal supports 6 are attached to mountain an array of anchors 7, skirting the corners of the mating workings. The rocks under the etapical pickups 6 are completely overwhelmed with metal mesh 3 or wooden pulls 8, In the assembly, the pickup 6 passes} by the top 5 of the first frame 5 anchored by the anchors 9 and fixed by the anchors 10.
