Description

Изобретение относитс к горной промышленности и может быть использовано дл управлени горным давлением при отработке крутых пластов полезного ископае.мого без посто нного присутстви людей в очистном забое.The invention relates to the mining industry and can be used to control rock pressure during mining of steep seams of mineral resources, without the constant presence of people in the clearing face.
Известен способ возведени опорных полос при отработке тонких крутых угольных пластов, -заключающийс в заполнении за пределами очистного забо мешков закладочным материалом, соединении этих мешков между собой гибкой св зью, например, тросом в одну линию и опускании затем с вентил ционного штрека в лаву с последующим распором за счет собственного веса закладочного материала в мешках 1.The known method of erection of support strips during the mining of thin steep coal seams is the filling of the filling material outside the cleansing bottom of the bag with the backfill material, the connection of these bags with each other by a flexible connection, for example, a cable in one line and then lowering from the ventilation drift into the lava followed thrust due to its own weight stowing material in bags 1.
Недостатки такого способа - высока трудоемкость работ и низка несуща способность опорных полос, вследствие деформации мешков с закладочным материалом под воздействием горного давлени в призабойной зоне.The disadvantages of this method are the high labor intensity and low bearing capacity of the support strips, due to the deformation of the bags with the backfill material under the influence of rock pressure in the bottomhole zone.
Известен.также способ возведени опорных полос из твердеющей сйеси при отработке тонких крутых угольных пластов длинными лавами по простиранию без посто нного присутстви людей в очистном забое.Known. Also the method of erection of support bands from hardening sysi when mining thin steep coal seams with long lava along strike without the constant presence of people in the clearing face.
заключающийс в размещении в выработанном пространстве параллельно очистному забою опалубки и дистанционной подаче в нее самотеком с вентил ционного штрека по вынимаемому на щтрек гибкому шлангу твердеющей смеси, при этом используют передвижную скольз щую опалубку, которую присоедин ют к корпусу выемочной машины и перемещают вверх вместе с ней 2.consisting in placing in the developed space parallel to the cleansing face of the formwork and remote feeding into it by gravity from the ventilation drift along the flexible hose of the hardening mixture removed onto the tongue, using a mobile sliding formwork that is attached to the body of the excavation machine and moved up with it 2
Недостатки этого способа - прив зка опалубки к комбайну, что не позвол ет применить способ к другим выемочным машинам , например стругам и пилам. Кроме того , производительность комбайна ограничиваетс временем отвердевани твердеющей смеси опорной полосы.The disadvantages of this method are the attachment of the formwork to the combine, which does not allow the method to be applied to other excavation machines, such as planes and saws. In addition, the productivity of the combine is limited by the solidification time of the hardening mixture of the support strip.
15 Цель изобретени - упрощение технологии возведени опорных полос за счет возведени их независимо от работы выемочной мащины.15 The purpose of the invention is to simplify the technology of building support strips by erecting them independently of the work of the excavation machine.
Поставленна цель достигаетс тем, что 20 опалубку, выполненную в виде м гкого рукава , размещают сразу по всей длине лавы на заданном рассто нии от очистного забо и оставл ют в выработанном пространствеThe goal is achieved by the fact that the 20 formwork, made in the form of a soft hose, is placed immediately along the entire length of the lava at a given distance from the clearing face and left in the developed space
