摘要
针对屯兰矿生产条件和围岩特点,分析沿空巷道顶板岩层运动特点及对沿空巷道围岩的影响,提出了沿空巷道锚梁网联合支护方案和充填体内钢筋网加固方法,增加沿空巷道围岩和充填体强度,实践证明沿空巷道变形满足生产要求。
Based on coal loss reasons, production condition and surrounding rock features in Tunlan mine, the study analyzes the movement of roof rock in gob-side retaining entry and its influence on the surrounding rocks. The paper presents the bolting-mesh-beam united support and inside steel-mesh reinforcement to increase the strength of surrounding rocks and the the entry deformation meets the production requirement. filling body. The practice proves that
