摘要
分析了沿空留巷顶板岩层运动的过程及其变形特征 ,明确了顶板岩层运动各阶段巷旁充填体的作用 ,根据充填体与顶板相互作用原理 ,确定了各阶段沿空留巷巷旁充填体支护阻力的控制设计原则 。
The motion process and deformation characteristics of roof rocks are analyzed for gob side entry and the function of roadside packing support during every stages of roof rock motion becomes clear. On the basis of interaction between packing support and roof rocks, the control design principle of retaining roadside packing supporting intensity is decided for gob side entry during each stage, and the mathematics model of support resistance and rational compressed volume is established.
