According to geological condition and survey of roadway workface in Qiyi Coal Industry, engineering analog method was adopted and combined support with bolting wire mesh [2] was applied including 12 roots anchor per row layout, with 6 roots on the roof and 3 roots in each side. Based on influence of deformation law of surrounding rock in gate roadway caused by anchor bolt support array pitch through numerical simulation study, optimal supporting row spacing was ensured which provided reference to supporting scheme determination.
