摘要
针对近距离采动影响巷道,运用FLAC2D软件,对不同情况下的跨采巷道稳定性进行数值模拟分析。初步探讨了近距离采动影响巷道围岩应力场的形成发展状况和传递分布特征,及考察方法的可行性和模型的可靠性,为确定合理的跨采方案提供有价值的指导或参考。
Considering short distance over mining roadway, the roadway stability at different position influenced by short distance over mining was analyzed by FLAC^2D finite element numerical simulation. Some aspects were discussed, such as the form and development of stress of the rock displacement around roadway under nearby overhead mining, and pressure distribution attribute, the feasibility of the method and the credulity of the model. The important and valuable reference was provided for maintaining and defining the rational over mining.
