摘要
张集煤矿14126工作面运输顺槽受上方工作面14138采动影响剧烈,故对其采取了加强支护方案设计,同时对设计的方案和设计的参数进行了简单介绍,并针对该设计方案利用离散元软件UDEC4.0就运输顺槽在2种不同采动计4种工况下的支护效果进行了模拟,并对比分析了14126工作面运输顺槽围岩的应力变化、位移变化以及塑性区的变化,得出当14138工作面回采后围岩应力稳定后再掘进14126运输顺槽时其总体变形是最小的,同时结果验证该支护方案设计是合理的.
Because of the violently mining influence of 14138 working face in Zhangji mine, a supporting design is adopted to strengthen it with some simple introductions on scheme design and parameters design in geteroad of 14126 working face. Aimed at the design plan by using discrete element software UDEC4.0 to simulate the gateroad supporting effect about four The stress, displacement from the simulation. The tunneled after the stress that the support scheme and plastic zone changes kinds of working conditions under two different mining projects. of the gateroad surrounding rocks are compared and analyzed results show that the overall deformation is the smallest of transport gateway when it＇ s of surrounding rock stability in the process of mining, at the same time the results verify design is reasonable.
