摘要
采用三角形载荷近似计算法则分析研究了目前公认的掩护式、支撑式和支撑掩护式三种液压支架的力学性能，指出这三种支架形式从力学结构上本是同一种类型，并且在采场管理上存在不少问题，应当用新型式支架去代替。
The mechanical characteristics of established shield, chock shield and chock-frame powered supports had been analyzed using triangular load approximate calculation in this paper, pointing out these three type powered supports are the same type from the point of view of mechanical structure, there are some problems in face control and they should be replaced by some new type supports.
