摘要
Abstract
For 21210 consecutive return air connection on the north and west wing track down the hill (overhead in inclined lane) corresponding minimum cross section rock pillars is 3.73 m, in order to ensure the safety of tunnel crossing construction period, by using fractional charge, divide second initiation, the anchor net supporting construction process, and the reinforcement method of theoretical analysis, and the deformation monitoring, thus ensuring the BoYanZhu be crossing the roadway under the safe use of the roadway drivage and the continuity of construction.关键词
