孤岛工作面沿空顺槽支护优化研究

摘要

Taking 1304 working face of Zhongxing Coal Industry Group (belongs to deep well island coal face) as research object,the paper has analyzed the characteristics of roadway deformation occurred in gateway excavation process,improved the original passive support mode, and optimized roadway section and bolt supporting parameters,which can meet the production needs.%以中兴煤业1304工作面（属于深井孤岛工作面）为研究对象，对其顺槽掘进过程中出现的巷道变形特征进行分析，对原有被动支护方式进行改进，优化巷道断面及锚杆支护参数，通过现场对围岩运移规律的监测可将巷道变形分为无影响区、一般影响区、剧烈影响区三个阶段，支护效果能够满足生产需要。
