摘要
液压支架是煤矿井下开采煤炭的重要支护设备，当煤层顶板具有冲击压力时，要求液压支架能与这种冲击压力相适应。通过理论计算来阐明液压支架的架型和立柱的抗冲击原理及液压支架的结构设计特点。
Hydraulic chocks are important supporting equipment for underground coal mining.Hydraulic chocks should withstand the shock pressure properly when the supported roof of coal seam bears the shock pressure.This paper expounds the principle of the selected type of hydraulic chock and the shockproof props,and the characters of the design of the structure of hydraulic supporting.
