在综采综放工作面超前支护和循环移架式超前支护液压支架研究现状分析的基础上,对循环移架式窄连杆轻型超前支护液压支架进行了设计研究,应用效果表明该液压支架稳定性高、抵抗水平力能力强,有效解决了超前支护液压支架对巷道顶板的反复支撑破坏的问题,具有广阔的推广应用前景。 Based on the analysis of the research status of advance support and advanced support hydraulic supports of fully mechanized top coal caving mining face, the design and research of the hydraulic support of the light guide support with narrow cross-link is carried out. The application results show that Hydraulic support high stability, strong ability to resist horizontal force, the effective support for the advanced support hydraulic support for the roof of the roadway repeatedly support the destruction of the problem, has broad prospects for the promotion.
