Abstract

Изобретение относитс к горному делу , а именно к очистным угледобывающим агрегатам дл крутых пластов. Цель -обеспечение возможности отработки пластов го- ризонтальными сло ми по челноковой схеме без перемонтажа крепи и повышение его поперечной устойчивости. В агрегате дл крутых пластов секции механизированной крепи св заны между собой с забойной и завальной сторон телескопическими стенками (ТС) 7 и 8. Корпусные части ТС 7 и 8 св заны с основанием 4 укосинами 9, а их выдвижные части св заны между собой штангами 10 и с верхн ками 1 верхними гидродомкратами 13 передвижки. На каждой ТС 7 и 8 смонтированы направл ющие 14 и 15 дл исполнительного органа. Верх- н ки 1 св заны гидростойками 2 с опорами 3, которые расположены в проеме оснований 4 и св заны с ними нижними гидродомкратами 12 передвижки. После отработки верхнего сло крепь переводитс в нижний слой и перемещаетс обратным ходом. При этом функции ТС 7 и 8 мен ютс . Бывша в верхнем слое завальна ТС становитс в нижнем слое забойной, а на ее направл ющих устанавливаетс исполнительный орган . 2 ил. сл сThe invention relates to mining, in particular to cleaning coal-mining units for steep seams. The goal is to ensure the possibility of mining the layers with horizontal layers according to the shuttle pattern without re-mounting the lining and increasing its lateral stability. In the unit for steep seams, the mechanized lining sections are interconnected with the downhole and underside sides of the telescopic walls (TS) 7 and 8. The hull parts of the TS 7 and 8 are connected to the base 4 with booms 9 and their pull-out parts are connected with each other by the rods 10 and with upper heads 1 upper hydraulic jacks 13 advances. Guides 14 and 15 for the executive body are mounted on each vehicle 7 and 8. The tops 1 are connected by hydraulics 2 to the supports 3, which are located in the opening of the bases 4 and are connected with them by lower jacks of the shifters 12. After the upper layer has been worked out, the lining is transferred to the lower layer and is moved in reverse. In this case, the functions of the TC 7 and 8 vary. The former in the upper layer of the injected vehicle becomes in the lower layer of the downhole, and the executive body is installed on its guides. 2 Il. cl
