Description
(54) ШТАНГОВАЯ КРЕПЬ(54) ROD CURTAIN
II
Изобретение относитс к креплению подземных горных выработок, а именно к штанговой крепи.FIELD OF THE INVENTION The invention relates to the fastening of underground mine workings, namely to roof support.
Известна штангова крепь, включающа стержень , снабженный винтовой резьбой 1.Known bolt, including the core, equipped with a screw thread 1.
Однако така крепь не обеспечивает устойчивости массива в случае наличи в- породах трещин.However, such lining does not ensure the stability of the massif in the presence of rocks in the cracks.
Известна также штангова крепь, включающа стержень, снабженный по всей длине винтовой резьбой дл ввинчивани в скважину 2.Also known is a bolt fastener comprising a rod provided along the entire length with a screw thread for screwing into the borehole 2.
Однако одной такой крепи недостаточно дл обеспечени устойчивости трещиноватых пород, но в случае их дополнительного тампонажа требуетс бурить дополнительные скважины и устанавливать в них иньекторы.However, such lining alone is not enough to ensure the stability of fractured rocks, but in the case of their additional tamponage, it is necessary to drill additional wells and install injectors in them.
Цель изобретени - повышение устойчивости трещиноватых пород посредством тампонажа их через установленную в скважине штанговую крепь.The purpose of the invention is to increase the stability of fractured rocks by means of their tamping through a sucker rod bolt installed in the well.
Это достигаетс тем, что в стержне с резьбой вьшолнены продольный и поперечные сквозные каналы.This is achieved in that the longitudinal and transverse through channels are made in the threaded rod.
На чертеже изображена 1итангоБа крепь.The drawing shows a lining.
Штангова крепь представл ет собой круглый стержень 1 длиной 1,5-2 м, диаметром 30-40 мм с продольным 2 и поперечными 3 CKBO3Hbi vra каналами, на котором имеетс винтова резьба 4 и 5. Диаметр резьбы 4 на хвостовике стержн 1 больше диаметра резьбы 5 на его остальной длине. Со стороны хвостовика стержн 1 в когще продольного канала 2 имеетс внутренн резьба 6 дл подключени к нему нагнетательного трубопровода.The shank support is a round rod 1 1.5-2 m long, 30-40 mm in diameter with 2 longitudinal and transverse 3 CKBO3Hbi vra channels on which there is screw thread 4 and 5. The diameter of the thread 4 on the shank of the rod 1 is larger than the diameter of the thread 5 on its remaining length. On the side of the shank of the rod 1, in the cogda of the longitudinal channel 2 there is an internal thread 6 for connecting a pressure pipe to it.

Штанговую крепь устанавливают следующим образом.Rod support set as follows.
Вслед за подвиганием забо горной выработки бур т скважины zmaMeTpoM, несколько меньiijHM диаметра резьбы стержн 1, и ввинчиваS ют его в них. После установки штанговой крепи нанос т набрызгбетонное покрытие, укрепл ющее приконтурный слой пород. Затем с отставанием на 10-20 м от забо к стержню 1 подключают нагнетательш 1й трубопровод и через штанговую крепь производ т тампонаж пород. При этом тампонажный раствор поступает через продольный канал 2 в поперечные каналы 3, а из них в трещины окружающих породFollowing the advancement of the intake development of the zmaMeTpoM drill hole, several smaller HI thread diameters of the rod 1 are screwed in into it. After installation, the sucker support is applied to spray the concrete coating, which strengthens the marginal layer of rocks. Then, with a lag of 10–20 m from the intake, rod 1 is connected to the supercharger, and tamping of rocks is performed through the sucker rod. When this cement slurry enters through the longitudinal channel 2 in the transverse channels 3, and from them into the cracks of the surrounding rocks
и, отвердева , повышает их устойчивость. За счет увеличенного диаметра резьбы 6 на хвостовике стержн 1 устье скважины герметизируетс и вытекашсе из нее тампонажного раствора предотвраидаетс .and, hardening, increases their stability. Due to the increased diameter of the thread 6 on the shank of the rod 1, the wellhead is sealed and the cement slurry out of it is prevented.
