Abstract: Taking 15101 mining face of Jiarui Coal，Shanxi Lu’an Group as engineering background and applying FLAC^3Dnumerical software，the characteristic of stress，deformation and failure of track roadway driven along floor in thick coalseam was simulated and analyzed．On the basis of this，surrounding rock control countermeasures for thick coalseam roadway was put forward and rational anchored bolt and cable supporting parameters were designed．Field application showed that supporting effect was excellent．
