摘　　要：介绍了马头门分层施工设计方案,从施工顺序、爆破方式、出矸等对马头门分层施工工艺进行了论述,采用了"锚网索喷一次支护+钢筋混凝土二次支护"的组合方式对马头门主体部分进行支护。结果表明,分层施工马头门,既能保证马头门施工安全和质量,又能降低施工难度,提高工效,缩短工期,是一种行之有效的施工方法。The design scheme of layered construction for ingate was introduced, the construction process was discussed through the analysis of construction sequence, blasting mode, and gangue transportation. The primary support applied the technology of shotcreting and bolting with wire mesh and the secondary support applied reinforced concrete. The results show that, layered construction is an effective construction method for ingate, with the safety and quality of ingate construction guaranteed, the construction difficulty reduced, the work efficiency improved, and construction period shortened.
