На фиг.1 показан общий вид крепи вкрест простирани пласта,-на фиг.2 - узел I на фиг, 2; на фиг.З - сечение А-А (возведение крепи в призабойном пространстве) на фиг.1; на фиг.4 то же,, возведение крепи за комбайномFigure 1 shows a General view of the lining across the strike of the reservoir, on figure 2 - node I in Fig, 2; on fig.Z - section AA (construction of lining in the wellbore space) in figure 1; figure 4 is the same, the erection of lining for the combine
Чтобы осуществить крепление .очистного пространства, используетс комплект гидрофицированных рам крепи, содержащих по две гидравлических стойки 1, шарнирно соединенных с гидрофицированным верхн ком 2. Рама опираетс на дерев нные стойки 3, закрепленные анкерами 4 к боковым стенкам очистного забо . Нижние конIl л гидравлических стоек снабжены опорно-удерживающим башмаком 5.To mount the cleaning space, a set of hydroficated support frames are used, each containing two hydraulic pillars 1 pivotally connected to a hydraulic upper 2. The frame rests on wooden pillars 3 fixed by anchors 4 to the side walls of the clearing face. The lower end of the hydraulic struts are equipped with a support-holding shoe 5.
Пласт разрабатываетс системой горизонтальных полос по простиранию с закладкой в восход щем пор дке с механизированной выемкой угл . Крепление очистного пространства осуществл етс рамной крепью б Выемка угл производитс комбайном 7, За комбайном на буровой установке 8 располагаетс крепеукладчик 9.The reservoir is developed by a horizontal strip system along the strike with a bookmark in an upward order with a mechanized excavation of coal. The cleaning of the cleaning space is carried out with frame support b. The coal is excavated by a combine 7. A combine layer 9 is located behind the combine on the drilling unit 8.
Способ возведени элементов крепи осуществл етс на двух рассредоточенных участках: в призабойном пространстве и за .ком байном.The method of erection of the lining elements is carried out in two dispersed areas: in the bottomhole space and behind the baycom.
В призабойном пространстве рама крепи 6, освобожденна от угл комбайном 7, поднимаетс на величину раздвижности гидравлических стоек, которые распираютс между верхн ком, прилегающим к потолочине забо , и дерев нными стойками 3, выступающими из закладочного массива. Гидравлические стойки 1 опираютс на дерев нные стойки 3 и поднимают верхн к 2 к потолочине забо и тем самым создаетс нужный предварительный распор Установленные рамы крепи б надежно удерживают стенки и потолочину очистного забо без применени временной крепи в сложных горно-геологических услови х.In the face-to-face space, the support frame 6, freed from the coal by the combine 7, rises by the amount of expansion of the hydraulic struts, which bulge between the top, adjacent to the ceiling of the slab, and the wooden struts 3 protruding from the backfill array. The hydraulic pillars 1 rest on the wooden pillars 3 and raise the top to 2 to the ceiling of the slab and thereby create the necessary preliminary strut. The installed lining frames will reliably hold the walls and ceiling of the clearing slab without the use of temporary lining in difficult geological conditions.
Совмещение процесса выемки угл с процессом возведени злементов крепи достигаетс тем, что вне зоны расположени комбайна 7 гидравлические стойки 1, поставленные в призабойном пространстве, попарно телескопически, сокращаютс на величину шага закладки и на их место устанавливаютс дерев нные стойки 3 с анкерами 4. Во врем выполнени работ по установке элементов крепи рамаCombining the coal extraction process with the construction of support elements is achieved by the fact that outside the location of the combine 7 hydraulic pillars 1, placed in the bottomhole space, are telescopically pairwise shortened by a step of bookmarking and wooden pillars 3 are installed in their place. installation of support elements
0 крепи 6 удерживаетс гидравлическим распором верхн ка 2 и крепеукладчиком 9. Бурение шпуров под анкера и установка их производитс буровой установкой 8.The 0 lining 6 is held by the hydraulic thrust of the upper 2 and the fastening 9. The drilling of holes for the anchors and their installation is carried out by the drilling rig 8.
5 При таком способе креплени очистного пространства обеспечиваетс надежное поддержание потолочины и боков выработки, что создает более безопасные услови труда.5 With this method of securing the cleaning space, the ceiling and the sides of the excavation are securely maintained, which creates safer working conditions.
