摘要
在研究液压支架与围岩相互作用的理论基础上,详细分析了支撑式液压支架、掩护式液压支架、支顶掩护式液压支架、支撑掩护式液压支架的外载荷,并从工作阻力、初撑力和结构形式三方面阐述了液压支架的选型原则。
On the basis of the study of the interaction between the hydraulic support and the surrounding rock, the support type hydraulic support, the cover type hydraulic support, the top cover type hydraulic support and the external load supporting the cover type hydraulic support are analyzed in detail, and the selection principle of the hydraulic support is explained from three aspects of the working resistance, the initial support force and the structure form.
