Abstract
Изобретение относитс к оборудованию дл креплени призабойного очистного пространства механизированными креп ми при разработке тонки.х угольных пластов крутого падени . Цель - повышение устойчивости крепи при работе на наклонных пластах. Механизированна пневмобаллонна кр.епь состоит из св занных между собой секций крепи. Кажда из секций включает поддерживающие 1 и упорные 4 гидростойки (ГС), перекрыти 2 с пазами и гидродомкраты (ГД) передвижени размещенные в верхней и нижней ложах несущего пневмобаллона 8. Перекрыти 2 св заны с траверсами, закрепленными на ГД передвижени . Кажда секци имеет дополнительную несущую ГС II, закрепленную на траверсах посредством державок 12. Между собой секции св заны посредством дополнительных ГД 13 передвижени . Передвижение секции производитс в основном усили ми ГД передвижени Посредством дополнительных ГД 13 создаютс дополнительные усили передвижени и регулируетс положение секции в плоскости пласта. 4 ил. со (ОThe invention relates to equipment for fastening the bottomhole cleaning space with mechanized supports in the development of thin steep coal seams. The goal is to increase the stability of support when working on inclined seams. The mechanized pneumocylinder is composed of interconnected lining sections. Each of the sections includes supporting 1 and thrust 4 hydraulic legs (HS), overlapping 2 with grooves and hydraulic jacks (DG) movements located in the upper and lower boxes of the supporting air bellows 8. Overlaps 2 are connected with cross-arms fixed to the DG movements. Each section has an additional carrier HS II, mounted on the cross arms by means of holders 12. The sections are interconnected by means of additional movement DG 13. The movement of the section is mainly carried out by the forces of the traveling movement. Through the additional driving force 13, additional movement forces are created and the position of the section in the formation plane is adjusted. 4 il. with (Oh
