摘要
基于现场实际观测结果 ,分析研究了沿空留巷顶板岩层运动的过程及充填体受力特征 ,根据充填体与顶板相互作用原理 ,确定了巷旁充填体支护阻力的计算原则 ,并建立了相应的支护阻力计算模型。
Based on the results of measurement, the motion process of roof rocks and support characteristics of roadside packing for gob side entry retaining are analyzed On the basis of interaction between packing support and roof rocks, the design principle of packing support resistonce is decided, and the mathematics model of support resistance is established
