Abstract
Изобретение относитс к горной промышленности и может быть использовано при слоевой разработке мошных пластов полезных ископаемых с применением гибкого межслоевого перекрыти . Цель - повышение надежности работы за счет исключени зазоров гибкого перекрыти при передвижке крепи. Механизированна крепь дл слоевой выемки МОШ.НЫХ пластов имеет секции, кажда из которых включает перекрытие 1, соединенное с опорами 2 посредство.м гидростоек 3. На верхнем ограждении 8 в кронштейнах 10 установлена кассета (К) I I с гибким элементом 12, на нижнем ограждении 9 - катки 13. Дополнительна К 14 с гибким элементом 15 размещена под К I 1 и посредством гибкой св зи 17 соединена со ставом конвейера 18. После сн ти стружки угл комбайном рештаки става забойного конвейера 18 последовательно передвигают на забой. Рештаки воздействуют на гибкую св зь 17 и увлекают за собой К 14. Рулоны гибких элементов 15 с них будут размат1)1- ватьс , наход сь между гидростойками 3. Затем передвигаютс секции крепи. При их передвижке разматываютс рулоны гибких элементов 12, расположенные в К И. Гибкие элементы 12 настилаютс на гибкие э.ю- менты 15 внахлестку и пepeкpывaюt межсекционные зазорь, образуюпаиес при настиле на почву гибких элементов 15. Надежное прижатие гибких элементов обеспечиваетс гидропатроном 7. 2 ил. (О (ЛThe invention relates to the mining industry and can be used in the layered mining of mineral deposits of minerals using flexible interlayer overlap. The goal is to increase the reliability of work by eliminating the gaps of the flexible ceiling when moving the supports. The mechanized lining for the layer excavation of the MESH reservoirs has sections, each of which includes an overlap 1 connected to the supports 2 by means of hydraulic posts 3. On the upper enclosure 8 in the brackets 10 a cassette (K) II with a flexible element 12 is installed, on the lower enclosure 9 - rollers 13. Additional K 14 with a flexible element 15 is placed under K I 1 and connected via a flexible link 17 to a conveyor bed 18. After the chips are removed, the coal from the bottom of the conveyor belt 18 is moved to the bottom face. The grids act on the flexible link 17 and carry around K 14. The rolls of flexible elements 15 will be unwrapped from them 1) between the hydraulic posts 3. Then the support sections are moved. When moving them, rolls of flexible elements 12, located in K I, are unwound. Flexible elements 12 lay on flexible e-cuments 15 overlap and intersect intersectional gaps, which form upon laying on the soil of flexible elements 15. Reliable pressing of flexible elements is provided by hydropatron 7. 2 silt (Oh (L
