摘要
为了探讨断层在围岩破坏及底板突水中的作用,采用RFPA2D-Flow数值模拟软件,分析了底板在有承压水作用的前提条件下,随着工作面的推进,不同断层倾角对采场围岩破坏和底板突水危险性的影响,得出了采场围岩失稳破坏的规律,并提出了工作面遇断层时的防治水措施,为王坡煤矿3号煤层的开采提供了科学依据.
To investigate the effect of fault on surrounding rock deformation and water inrush from coal floor, by using software of RF-PA2D-Flow,the influence of different dips of fault on surrounding rock deformation and water inrush from coal floor was analysed as the working face going ahead under the condition that affected by confined water. The law of surrounding rock instability and failure was reached,water controlling measures when working face cross faults were also proposed. All this can provide scientific basis for 3# coal seam mining in Wangpo Coal Mine.
