为了较为准确计算顶板来压阶段液压支架的载荷,根据来压阶段岩层结构模型,引用三铰拱式模型和关键层理论,对这种恶劣情况下的液压支架的动静载荷进行计算,得出了支架所受载荷与煤层其他参数之间的关系,为安全阀选择提供理论依据。
In order to accurately calculate the load of the hydraulic support during the pressing stage of the roof, the dynamic and static loads of the hydraulic support under such adverse conditions are calculated according to the rock-layer structure model of the compression stage, the three-hinge arch model and the key layer theory The relationship between load and the other parameters of coal seam provides the theoretical basis for the selection of safety valve.
