摘　　要：ZZ13000/28/60型液压支架应用于同煤集团坚硬顶板条件下,针对支架的受力状况,建立了支架的三维实体模型,分析了在偏载、扭转工况下支架的受力情况。结果表明,ZZ13000/28/60型液压支架适合同煤集团坚硬顶板的要求。ZZ13000/28/60 type hydraulic support used in hard roof conditions of Datong Coal Group Company. According to the stress of the stent, established the bracket of the threeimensional entity model and analyzes the force of hydraulic support, under torsion and offset load conditions. The results show that, hydraulic support meet the requirement of hard roof in Datong Coal Group Company.
