摘　　要：基于结构动力学理论,对近水平煤层及大倾角综放开采中综放支架的稳定性进行了分析,建立了相应的力学模型,并推出综放支架的运动学公式,对影响支架稳定性的因素进行了分析。Stabilities of synthetical supports in the fully mechanized caving with nearly horizontal and large dip angle coal seam are analyzed based on the theory of structural dynamics. The corresponding mechanical model is established and kinematics formula of synthetical supports is derived.The factors affecting the stability of synthetical support are analysed.

关 键 词：结构动力学 大倾角综放支架 单自由度 支架工作阻力
