Numerical Simulation Study on Combined Supporting Scheme of Bolts and Anchor Cable

Aiming at the face roadway 22109 of Cuncaota coal mine, using FLAC(3D) numerical simulation software, 19 of 5 groups about bolt and anchor combined support schemes were analysed and compared, and the reasonable scheme of phi 18x2000mm thread steel bolt and phi 17.8x6500mm anchor cable combined support was obtained. Support result of this scheme was analysed with FLAC(3D) software, 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.
