(54) КРЕПЬ ДЛЯ ЗАХОДОК ПРИ СТОЛБОВОЙ СИСТЕМЕ(54) FASTENING FIXTURES AT COLUMN SYSTEM
РАЗРАБОТОКDEVELOPMENT

Изобретение относитс к горной промышленности , в частности к креплению очистных выработок при разработке пластовых месторождений полезных ископаемых системой длинных столбов с выемкой заходками.The invention relates to the mining industry, in particular, to the fastening of the clearing workings during the development of stratal mineral deposits by a system of long pillars with a recess by stopping.
По основному авт. св. № 649856 известна крепь дл заходок при столбовой системе разработок, включающа верхн к со стойкой и соединительный узел, причем соединительный узел выполнен в виде сьемного П-образной формы с полками, на которых размещен верхн к со стороны заходки 1.According to the main author. St. No. 649856 is known fasteners for stoppers at the pole system of development, including a top with a stand and a connecting node, the connecting node being designed as a removable U-shaped with shelves on which is placed upper to the side of the stopper 1.
Недостатком известной крепи вл етс то, что из отработанной заходки извлекают и вынос т в откаточный штрек подвальные стойки вместе с соединительными узлами, а также дерев нные верхн ки, дл использовани которых заново вновь занос т их в новую заходку. Это приводит к больщому расходу крепежного леса и значительному повышению объема работ по креплению. Кроме того, указанные способы креплени заходок не обеспечивают второго выхода из очистной выработки и проветривани за счет общешахтной депрессии, дл нормальной работы необходимо дополнительно устанавливать вентил торы местного проветривани , которые требуют дополнительного расхода средств и объема работ.A disadvantage of the known lining is that the basement racks, together with the connecting nodes, as well as wooden tops, for the use of which they are reintroduced into the new approach, are removed from the used stowage and taken out into the haul road. This leads to a greater consumption of fastening wood and a significant increase in the scope of work on the mount. In addition, these methods of fastening the inlets do not provide a second way out of the clearing generation and ventilation due to a general mine depression, for normal operation it is necessary to additionally install local ventilation fans, which require additional expenditure of funds and amount of work.
Каждый рабочий блок (камера, лава), в котором ведетс очистна выемка, должен иметь не менее двух независимых, ничем не загроможденных выходов на поверхность или на рабочие горизонты, причем в последнем случае один из них - на откаточный, а другой - на вентил ционный горизонты.Each working unit (chamber, lava), in which the clearing recess is conducted, must have at least two independent, uncrowded exits to the surface or to the working levels, and in the latter case one of them is for the haulage and the other for ventilation. horizons.

Цель изобретени - снижение расхода крепежного материала и уменьщение трудоемкости работ по креплению.The purpose of the invention is to reduce the consumption of fastening material and reduce the labor intensity of the mounting work.
Цель достигаетс тем, что в крепи П-образный элемент выполнен с консолью, расположенной со стороны обрушени породы, The goal is achieved by the fact that, in the support, the U-shaped element is made with a console located on the side of the rock collapse,
15 и щарнирно соединен с верхн ком.15 and hinged to the top of the cc.
На фиг. 1 изображен пример реализации способа креплени заходок; на фиг. 2 - породный элемент с верхн ком.FIG. 1 shows an example of an implementation of a fastening method; in fig. 2 - rock element with the upper com.
Крепь дл осуществлени данного спосо20 ба представл ет собой неполную крепежную раму, котора состоит из подзавальной стойки I, стойки 2 целикового бока, соединительного узла 3, металлического верхн каThe support for the implementation of this method is an incomplete fastening frame, which consists of a pillar base I, a two-sided pillar, a connecting unit 3, and a metal top
