摘　　要：以三交河矿掘进工作面软弱复合顶板支护为工程背景,分析了软弱岩体和层状岩体的变形机理,得到了软弱复合顶板的移动变形规律,并针对顶板软弱岩层不同位置进行了不同支护方案设计,研究结果为软弱复合顶板煤巷支护提供了新的思路,保证了巷道掘进工作的安全运行。This paper takes the weak composite roof support as the engineering background for the Sanjiaohe Mine working face, analyzes the deformation mechanism of the soft rock and the layered rock mass, obtains the deformation law of the weak composite roof, and carries out the different positions of the soft rock in the roof. The design of different supporting schemes provided a new idea for the support of the soft composite roof coal roadway and ensured the safe operation of roadway excavation work.
