Aiming at the face roadway 22109 of Cuncaota coal mine, using FLAC3Dnumerical simulation software, 19 of 5 groups about bolt and anchor combined support schemes were analysed and compared, and the reasonable scheme of φ18×2000mm thread steel bolt and φ17.8×6500mm anchor cable combined support was obtained. Support result of this scheme was analysed with FLAC3Dsoftware, the result show that this scheme can support the roadway effectively. Practical application show that this scheme can achieve the security, economical and effective support result, and can be used in this type of roadway.
