地下厂房开挖为建造位于地下的厂房，将土和岩石松动、破碎、挖掘和运输出渣的工程。地下厂房一般断面较大，在开挖过程中，保持顶拱安全和高边墙稳定的问题十分重要，施工中要根据具体条件采用相应的施工方法。主要的方法是：①钻孔爆破法。一般先开挖顶拱和进行顶拱支护、衬砌,然后再进行下部分层分台阶的开挖。开挖后立即进行锚喷。如日本今市抽水畜能电站的地下厂房,宽33.5m、高51m、长160m,首先在顶部开挖宽8m、高7.5m的中心导洞，全长挖完后,再扩挖加宽到22m,然后用阶梯式,逐渐加深加宽洞室的主体部位（见图）。②光面爆破和预裂爆破技术。③锚喷支护。对高边墙则采用预应力锚索、锚杆和喷射混凝土相结合的结构，并可作为永久支护。④将新奥法（见隧洞开挖）的原则应用于大断面地下厂房的开挖。如德国瓦尔德克二级抽水蓄能电站的地下厂房，宽33.5m、高54m、长106m，地质条件较差，按新奥法的原则施工，取得良好结果。⑤采用汽车和带式输送机运输。地下厂房与各项联通的洞室群错综复杂，需综合考虑厂房本身及其他洞室的交通运输方式，合理选择出渣方式。一般采用汽车或带式输送机，以汽车运输方式居多。还可利用竖井，从底部的作业洞出渣。⑥预留支撑岩柱。在地质条件差,开挖跨度大的情况下,可采用在中间预留岩柱，最后挖除的办法。如中国龙羊峡水电站厂房安装间在地下,最大开挖跨度38.2m、高38m、洞长47m。由于围岩受断层切割,地质条件复杂,施工中利用预留岩柱支撑，分段开挖，分段衬砌，终于安全建成。
