摘要
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 calculate the load of the hydraulic support in the stage of increasing roof pressure more accurately. According to the rock structure model during the period of pressure and reference three hinged arch model and the key strata theory, calculated dynamic and static the load of hydraulic support under this hostile environment and the relationship of the load and the coal seam's other parameters is obtained. The theoretical basis for the accurate calculation of the load of the hydraulic support and the choice of the safety valve is provided.
