摘　　要：为研究两柱掩护式综放支架的工作特性及对工作面条件的适应性,掌握支架工作阻力的循环变化规律,针对现场工作面端面顶板的控制效果以及支架的工艺性能进行了数据实测。研究表明:两柱式支架工作阻力以增阻状态为主,支撑效率大幅提高;能够阻止顶梁的低头运动,保持支架的稳定;可以提供更高的工作阻力和水平力,取得更好的端面控顶效果;控制结构简单、后部放煤空间大、移架和放煤速度快,为进一步提高工作面回采效率创造了条件。Job characteristics for the study of the two leg sublevel caving shield support and the working condition of adaptability, cyclical variation law of the working resistance of the supports, the control effect of the top roof of the working face and process properties of the scaffold were measured data. Research shows that：two column support working resistance to increase resistance state, support efficiency is greatly im-proved;to prevent the roof bow movement, to maintain the stability of the bracket;can provide higher working resistance and the horizontal force, better face roof control effect;the control structure is simple, the rear caving space, frame shift and put coal speed, creates the conditions for further improve the mining efficiency.
