摘　　要：通过分析甲玛矿区破碎软弱岩体巷道的失稳模式,针对4个级别的岩体分别选择相应的支护方式,在确定对应支护方式的基础上,初步选定Ⅱ~Ⅳ级岩体的支护参数,采用数值模拟方式对初选的支护参数进行了对比优化分析,最终推荐了Ⅱ~Ⅳ级岩体巷道支护参数,模拟研究结果为甲玛矿区支护设计、施工提供技术指导。By analyzing the instability mode of the broken soft rock roadway in Jiama mining area,the corresponding support methods are selected for the four grades of rock masses.On the basis of determining the corresponding support mode,the preliminary selection of Ⅱ~Ⅳ rock mass is recommended.The primary support parameters were numerically simulated to compare and optimize the primary support parameters.Finally,the support parameters of the Ⅱ~Ⅳ rock roadway were recommended.The simulation results are the design and construction of the support of Jiama mine.

关 键 词：失稳模式 分级支护 支护参数 数值模拟
