Abstract
Изобретение относитс к горному делу и может быть использовано дл выемки пластов угл наклонного падени . Цель - повышение уровн безопасности ведени работ при комбайновой выемке полезного ископаемого на пластах наклонного падени . Устройство включает закрепленный к перекрытию 4 гибкими элементами /ГЭ/ защитный элемент. Он выполнен в виде горизонтального желоба 6, прикрепленного к перекрытию с помощью опор 4 вала 5, размещенного между ГЭ 11, которые прикреплены к кра м горизонтального желоба и Т-образных стержней 7. Горизонтальные полки стержней 7 установлены в желобе 6 и расположены вдоль продольной оси перекрыти . Вертикальные части св заны между собой гибкими ст жками 10 и выполнены с шарнирно закрепленными нижними концами. При ударе об устройство кусков угл и валунов оно перемещаетс в сторону удара, враща сь на валу 5, и сжима ГЭ 11, расположенные с падающей стороны пласта. При этом раст гиваетс ГЭ 11, расположенные с восстающей стороны пласта. Этим замедл етс или останавливаетс движение кусков вдоль лавы. 2 ил.The invention relates to mining and can be used for excavating seams of oblique incidence. The goal is to increase the level of safety of operations during the combine mining of minerals on the layers of oblique incidence. The device includes 4 flexible elements / GE / protective element fixed to the ceiling. It is made in the form of a horizontal gutter 6 attached to the overlap by means of supports 4 of the shaft 5 placed between GE 11, which are attached to the edges of the horizontal gutter and T-shaped rods 7. The horizontal shelves of the rods 7 are installed in the groove 6 and are located along the longitudinal axis shut off. The vertical portions are interconnected by flexible straps 10 and are made with hinged lower ends. When striking a device of pieces of coal and boulders, it moves in the direction of impact, rotating on the shaft 5, and compressing GE 11, located on the falling side of the formation. This extends GE 11 located on the rising side of the formation. This slows down or stops the movement of the pieces along the lava. 2 Il.
