摘　　要：针对岳城煤矿2301工作面巷道顶板离层有"网包"、锚索补强支护效果不明显等问题,采用顶板窥视技术进行了原因分析,针对顶板的软岩夹层特性制订了锚网梁联合支护方案并现场试验。结果表明,采用该支护设计后,巷道围岩保持了很好的完整性,顶底移近量最大为33 mm,两帮移近量最大为128 mm,提供的支护参数能满足生产和安全要求。In view of the problems of"mesh bag"in the roadway roof separation of 2301 working face in Yuecheng Coal Mine and the unclear effect of anchor cable reinforcement and support,the cause is analyzed by using the roof peeping technology.According to the characteristics of soft rock interlayer of the roof,the bolt mesh beam combined support scheme is formulated and tested in the field.The results show that after adopting the support design,the surrounding rock of the roadway maintains good integrity.The maximum displacement of the top and bottom is 33 mm,and the maximum displacement of the two sides is 128 mm.The support parameters provided can meet the production and safety requirements.
